Advanced Transfer Scenarios

This guide covers complex transfer scenarios that require special handling in RefriTrak. These workflows ensure EPA compliance while accommodating real-world situations like equipment retrofits, reclamation, and retroactive data entry.

Refrigerant Retrofits

A retrofit occurs when you change the refrigerant type in a circuit (e.g., replacing R-22 with R-410A). This is a special transfer type that resets the EPA compliance baseline.

Why Retrofits Are Different

EPA leak rate calculations compare additions to the circuit's full charge. When you retrofit:

The refrigerant type changes
The full charge amount usually changes
Previous leak rate history no longer applies to the new refrigerant
A new compliance baseline starts

RefriTrak creates a RETROFIT transfer that acts as a checkpoint, resetting the EPA calculation start date for the new refrigerant.

Retrofit Workflow

Step 1: Choose Direction

Select "Transfer In (Charging)"
Continue

Step 2: Select Source Cylinders

Add cylinders containing the NEW refrigerant type
System will NOT warn about refrigerant mismatch (retrofit is intentional)
Set transfer amounts from each cylinder
Continue

Step 3: Retrofit Configuration

Check "This is a refrigerant retrofit"
Enter new full charge amount for the retrofitted system
- This becomes the new baseline for EPA calculations
- Typically different from old refrigerant's full charge
- Check equipment nameplate or manufacturer specs

Step 4: Transfer Details

Set purity (typically virgin refrigerant for retrofits)
Link to job (recommended - major service event)
Notes should document:
- Old refrigerant type and amount recovered
- Reason for retrofit (R-22 phase-out, efficiency upgrade, etc.)
- Equipment modifications made
- New refrigerant type
Continue

Step 5: Review

Verify new full charge amount is correct
EPA Impact shows: "This retrofit will reset the EPA compliance baseline"
Submit

What Happens:

Circuit refrigerant type updates to new type
Full charge updates to new amount
RETROFIT transfer is created
EPA leak rate calculations start fresh from this date
Previous transfers remain in history but don't affect new refrigerant's leak rate

Important: Always recover the old refrigerant BEFORE performing the retrofit transfer. Record two transfers:

CIRCUIT_TO_CYL (recovery of old refrigerant)
RETROFIT (charging with new refrigerant)

Reclamation Transfers

Reclamation is when you remove refrigerant from a circuit and send it to an EPA-certified reclamation facility for disposal or processing.

When to Use Reclamation

Decommissioning equipment
Contaminated or mixed refrigerant that can't be reused
Customer is disposing of equipment
Refrigerant being sent out for reclamation service

Reclamation Workflow

Step 1: Choose Direction

Select "Transfer Out (Recovery)"
Continue

Step 2: Choose Recovery Type

Select "Reclamation"
This indicates refrigerant is leaving your possession for reclamation
Continue (skips cylinder selection)

Step 3: Reclamation Details

Amount:

How much refrigerant you recovered for reclamation
This is what you're sending to the reclamation company

Optional Loss Amount:

If some refrigerant was lost during the process (unrecoverable)
Creates a separate LOSS transfer automatically
Common scenarios:
- Catastrophic leak before you could recover
- Refrigerant in components you couldn't access
- Offset during decommission

Link to Job:

Recommended for decommission projects
Tracks customer billing and service history

Notes - Document thoroughly:

Reclamation company name
Certificate number or documentation reference
Equipment disposition (decommissioned, replaced, etc.)
Reason for reclamation
Any loss circumstances

Step 4: Review & Submit

Review shows:

Type: Reclamation
Amount sent to reclamation
Optional loss amount (if entered)
Circuit charge before and after
EPA Impact: "Reduces circuit charge. Loss amount (if any) counts toward leak rate."

Submit to create transfer(s).

Result:

RECLAMATION transfer created for amount sent to reclamation
LOSS transfer created if you entered a loss amount
Circuit current charge reduces to zero (typically - for decommission)
Compliance history preserved for future audits

Best Practice: Keep documentation from reclamation facility (certificates, receipts) attached to the job or customer notes for EPA audit purposes.

Recharge Transfers (EPA-Exempt)

A recharge is when you recover refrigerant from a circuit during service, then put the SAME refrigerant back into the SAME circuit. EPA exempts this from leak rate calculations because no net refrigerant was added.

Qualifying Criteria for Recharge

ALL of these must be true:

Refrigerant was previously recovered from THIS circuit
Same refrigerant is being returned to THIS circuit
Refrigerant remained in your possession (didn't leave your facility)
You have a matching CIRCUIT_TO_CYL transfer from the same circuit

Common recharge scenarios:

Recovered refrigerant to perform compressor replacement
Removed charge to repair leak, then recharged after fix
Temporary recovery for equipment move or modification

What doesn't qualify:

Adding NEW refrigerant after a repair (use standard Transfer In)
Recovered from Circuit A, charging into Circuit B (different circuits)
Refrigerant was sent out for reclamation/testing (left your possession)
Mixing recovered with virgin refrigerant (partial recharge not supported)

Recharge Workflow

Step 1: Choose Direction

Select "Transfer In (Recharge - EPA Exempt)"
System shows warning: "Only use this if refrigerant was recovered from THIS circuit"
Continue

Step 2: Select Source Cylinders

Add the cylinder(s) containing the recovered refrigerant
Must be the same refrigerant type as circuit
Set transfer amount
Continue

Step 3: Transfer Details

Purity:

Typically "Untested" for recovered refrigerant
Select tested purity if you had it tested

Link to Job:

Required - Link to the same job where you recorded the initial recovery
Proves this is the same refrigerant from the same circuit

Notes - Must document:

Reference the original CIRCUIT_TO_CYL transfer date
Confirm this is the same refrigerant
Note any purity testing performed
Document repair work performed between recovery and recharge

Step 4: Review & Submit

Review shows:

Type: Recharge (EPA Exempt)
Source cylinders and amounts
Circuit charge before and after
EPA Impact: "This recharge is exempt from EPA leak rate calculations"

Submit to create RECHARGE transfer.

Critical: If you add ANY additional refrigerant beyond what you recovered, you must record TWO transfers:

RECHARGE transfer for the recovered amount (exempt)
Transfer In (Charging) for the additional amount (EPA tracked)

Manual Transfer Entry

Manual transfers are for retroactive data entry when you added refrigerant but didn't track which cylinder it came from at the time.

When to Use Manual Entry

Entering historical data when migrating to RefriTrak
Technician added refrigerant but didn't record source cylinder
Emergency service where tracking was impractical
Correcting missing transfer records

Two Types of Manual Entry

Manual Add (EPA Tracked):

Refrigerant addition that COUNTS toward leak rate calculations
Most common manual entry type
Use when you added NEW refrigerant to the circuit

Manual Add (Recharge - EPA Exempt):

Refrigerant addition that does NOT count toward leak rate
Only use if this was a recharge (recovered from same circuit)
Rare - you should have recorded the original recovery

Manual Entry Workflow

Step 1: Choose Direction

Select "Manual Entry"
Continue

Step 2: Manual Transfer Type

Select "Manual Add (EPA Tracked)" OR
Select "Manual Add (Recharge - EPA Exempt)"
Choose carefully - affects EPA compliance calculations
Continue

Step 3: Manual Entry Details

Amount:

How much refrigerant was added
Required field
Use your best estimate if exact amount unknown

Notes - REQUIRED (minimum 10 characters):

Why this is required: Manual entries lack the accountability of cylinder tracking. Detailed notes are essential for EPA audit defense.
Document:
- Date the actual transfer occurred (if different from today)
- Why cylinder wasn't tracked at the time
- Source of refrigerant (if known)
- Circumstances requiring manual entry
- Any supporting documentation (invoice, service ticket)

Example good notes:

"Added approximately 3.5 lbs R-410A on 2/15/2026 during emergency leak repair. Cylinder tracking unavailable at customer site. Invoice #12345 confirms refrigerant purchase."

Current Charge After (Optional but Recommended):

Enter the circuit's actual current charge after this manual addition
Creates a CORRECTION transfer - a reconciliation checkpoint
Helps correct drift between calculated and actual charge
Use if you verified actual charge with gauges or recovery

Link to Job:

Select associated job if available
Helps with audit trail

Step 4: Review & Submit

Review shows:

Type: Manual Add (EPA Tracked) or Manual Add (Recharge)
Amount
Notes (must be 10+ characters)
Optional correction checkpoint
EPA Impact: Shows whether this counts toward leak rate

Submit to create transfer (and optional CORRECTION transfer).

What Happens:

Manual transfer created with your entered amount
If you entered "Current Charge After," a CORRECTION transfer sets the actual charge
Circuit current charge updates
Transfer marked as manual entry in history

Correction Checkpoints (Reconciliation)

When you enter a "Current Charge After" value, RefriTrak:

Creates your manual transfer (adds/subtracts the amount you entered)
Creates a CORRECTION transfer that sets the circuit's actual current charge
Any difference between calculated and actual charge is reconciled

Example:

Circuit calculated charge: 22 lbs (based on transfer history)
You added 3 lbs manually
You measured actual charge after: 24 lbs
RefriTrak calculates: (22 + 3) = 25 lbs expected
You said it's actually 24 lbs
CORRECTION transfer adjusts by -1 lb to reconcile

This corrects any accumulated errors from estimation or unrecorded losses.

De Minimis Loss Tracking

EPA allows excluding "de minimis" losses from leak rate calculations. These are small amounts of refrigerant that remain in hoses, fittings, and gauge ports during normal service - unavoidable losses that don't represent equipment leaks.

What Qualifies as De Minimis

Refrigerant in charging hoses after disconnect
Refrigerant in gauge ports and service valves
Refrigerant in recovery equipment (non-recoverable residual)
Small amounts from necessary purging during service

What doesn't qualify:

Actual equipment leaks
Refrigerant vented intentionally
Losses from improper procedure
Spills or accidents

How RefriTrak Detects De Minimis

RefriTrak uses cylinder gross weight tracking to automatically calculate de minimis losses:

The Math:

Cylinder gross weight before transfer (initial)
Minus: Refrigerant transferred (what you recorded)
Minus: Cylinder tare weight (empty cylinder weight)
Equals: Expected remaining weight
Compare to: Actual gross weight after transfer (what you measured)
Difference = De minimis loss

RefriTrak automatically creates a DE_MINIMIS transfer for the difference.

Recording Gross Weights

During Transfer In (Charging):

After selecting cylinders and amounts, you'll reach the Gross Weight Update step (only appears if you're partially emptying cylinders).

For each cylinder:

Before transfer: Note the cylinder gross weight (or RefriTrak uses last known weight)
After transfer: Weigh the cylinder
Enter the gross weight after in the form
Leave blank if you don't have a scale

RefriTrak shows:

Cylinder name
Amount you're transferring from this cylinder
Expected remaining in cylinder
Field to enter actual gross weight after

Submit weights to continue.

What Happens:

RefriTrak calculates expected vs actual remaining
If difference > 0.1 lbs, creates DE_MINIMIS transfer
DE_MINIMIS transfer is excluded from EPA leak rate calculations
Notes auto-generated: "De minimis loss detected via gross weight tracking (expected: X lbs, actual: Y lbs)"

Best Practices for De Minimis Tracking

Use a scale - Most accurate method
Record tare weight on cylinders (empty weight) - improves accuracy
Weigh immediately after transfer - before cylinder temperature changes
Account for hose volume - Standard 1/4" hose holds ~0.1-0.15 lbs per 10 feet
Document - Notes help explain reasonable de minimis amounts during audits

When Not to Use Gross Weight Tracking

You can skip gross weight entry if:

You don't have a scale available
You fully emptied all cylinders (no de minimis - all refrigerant transferred)
You're doing bulk transfers where precision isn't critical
Time constraints during emergency service

The transfer will still complete normally; you just won't get automatic de minimis detection.

Replacement Charges After Loss

When you've documented a refrigerant loss and now need to recharge the circuit, RefriTrak can link the replacement charge to the original loss for clear EPA documentation.

Why Link Replacement Charges

EPA wants to see:

Loss documented (when leak was discovered)
Repair performed (what you fixed)
Replacement refrigerant added (recharging after repair)

Linking these creates a clear audit trail showing you properly documented and addressed the leak.

Replacement Charge Workflow

Scenario 1: Loss Transfer Already Exists

You previously recorded a LOSS transfer. Now you're adding replacement refrigerant.

During Transfer In (Charging):

Step 3 - Transfer Details:

Check "Replacing a documented loss"
Dropdown appears showing recent LOSS transfers for this circuit
Select the loss transfer you're replacing
System automatically links this charge to that loss
Notes auto-populate: "Replacement charge for [X] lbs loss on [date]"
Add any additional notes
Continue and submit

Result:

Transfer created and linked to the loss transfer
Clear audit trail: loss → repair job → replacement charge
EPA sees proper documentation sequence

Scenario 2: Loss Not Yet Recorded

You're adding refrigerant and realize you forgot to document the loss first.

During Transfer In (Charging):

Step 3 - Transfer Details:

Check "Replacing a documented loss"
Leave dropdown on "Create New Loss"
Enter Loss Amount field
System will create a LOSS transfer first, then link your charge to it
Add notes documenting:
- When loss occurred
- How leak was discovered
- Repair performed
Continue and submit

Result:

LOSS transfer created with your entered amount
Charging transfer created and linked to that loss
Both transfers created in one operation
Proper EPA documentation even though you recorded them together

Replacement Charge Best Practices

Always document losses separately - Record LOSS transfer when you discover it, not later
Link replacement charges - Don't create a standalone charge for a post-repair recharge
Document repairs - Note what was fixed in the job and transfer notes
Match amounts - Replacement amount should roughly match loss amount (may differ slightly)
Timeline clarity - Notes should explain sequence of events

Common Advanced Scenarios

Scenario: Retrofit with Partial Recovery

Situation: Customer wants R-22 system converted to R-410A, but some R-22 escaped before you could recover it.

Process:

Record LOSS transfer for R-22 that escaped
Record CIRCUIT_TO_CYL transfer recovering remaining R-22
Record RETROFIT transfer charging with R-410A (set new full charge)
Link all three to same job

Result: Complete audit trail showing old refrigerant disposition and new baseline.

Scenario: Equipment Decommissioned with Leak

Situation: Equipment is being scrapped. Some refrigerant leaked out, rest goes to reclamation.

Process:

Record LOSS transfer for leaked amount
Record RECLAMATION transfer for recovered amount
- Include loss amount in reclamation form
Link to decommission job

Result: Circuit charge goes to zero, all refrigerant accounted for.

Scenario: Manual Entry for Historical Migration

Situation: Setting up RefriTrak, need to enter 2 years of service history for EPA compliance.

Process:

For each historical service where refrigerant was added:
- Create Manual Add (EPA Tracked) transfer
- Use actual date in notes: "Historical entry: Added 2.5 lbs on 4/12/2024 per invoice #789"
- Enter accurate amounts from invoices/records
After all historical entries, create CORRECTION transfer
- Set "Current Charge After" to actual current charge (measured today)
- Reconciles any discrepancies

Result: 12-month leak rate calculations include historical additions, compliant with EPA requirements.

Scenario: Recharge After Compressor Replacement

Situation: Recovered 18 lbs for compressor replacement, replacing with same 18 lbs after repair.

Process:

Record CIRCUIT_TO_CYL transfer: 18 lbs recovered
Perform compressor replacement (document in job)
Record RECHARGE transfer: 18 lbs back to circuit
- Link to same job
- Reference original recovery transfer in notes

Result: No net addition, no EPA leak rate impact.

Tips for Complex Transfers

Plan the sequence - Think through all transfers before starting
Link to jobs - Jobs tie complex multi-transfer operations together
Detailed notes - Future auditors (EPA or internal) need context
Use correct types - Wrong transfer type = wrong EPA calculations
When in doubt, separate - Multiple simple transfers better than one complex incorrect transfer
Review before submitting - Transfers are permanent
Keep external docs - Reclamation certificates, test results, invoices as job attachments
