Process chillers: separate the equipment sale from refrigerant work

A process chiller can be a valuable machine in its own right, or an essential part of another machine's package. Settle which applies before inviting offers. Selling the chiller separately may leave a laser, moulding machine or production line without the cooling equipment described in its listing.
The first task is to identify the unit and its connections. The second is to agree who will assess and undertake any specialist work. A sale description should not quietly turn into an instruction for the buyer's driver to disconnect refrigerant equipment.
Record the duty, as well as the badge
Photograph the manufacturer's plate, model, serial number and accessible refrigerant label. Copy the wording accurately, including units. Keep the manufacturer's manual and any service reports with the record.
Cooling capacity needs its conditions. Applied Thermal Control explains that a chiller's available cooling capacity changes with process-fluid and ambient temperatures. A nominal kilowatt figure therefore needs its reference conditions. It is not a promise that the unit will remove the same amount of heat from a different process.
Describe the previous application in plain terms: what the chiller served, whether it was dedicated or shared, and what recorded operating information survives. Mark a temperature copied from an old production sheet as a historical setting. Do not describe it as the correct setting for a future installation.
A chiller offered with a fibre laser cutting machine should be identified in that machine's inventory. The same applies to an injection moulding machine whose catalogue photographs show nearby auxiliaries.
Use one handover sheet
| Subject | Record before advertising | Who needs to resolve a gap? |
|---|---|---|
| Identity | Maker, model, serial and photographs | Seller and manufacturer if unclear |
| Past cooling duty | Served equipment and dated operating records | Buyer’s process engineer assesses a new duty |
| Equipment boundary | Chiller, pump, tank, hoses and controls included | Seller and sale organiser |
| Refrigerant history | Label details and available service or leak records | Suitably qualified refrigerant contractor |
| Electrical and fluid connections | Drawings, connection locations and shared services | Relevant competent contractors |
| Collection condition | Present location and proposed released state | Seller, contractors and transporter |
The final row matters. “Buyer to collect” leaves too much unsaid if nobody has agreed whether the unit will be disconnected, prepared and accessible when the transporter arrives.
Agree the specialist work before the collection date
For equipment in Great Britain, GOV.UK guidance on F-gas recovery requires a suitably qualified technician for recovery work. That does not mean every chiller sale requires the same work. The contractor must assess the actual unit, refrigerant and proposed move. For Northern Ireland, use DAERA’s F-gas guidance and ask the contractor to confirm the applicable requirements.
Ask for a written scope that names the equipment, the work required and the records to be supplied afterwards. Keep refrigerant work separate from electrical isolation, process-fluid arrangements and transport, even if one contractor coordinates several tasks.
The seller should confirm who appoints each contractor and when the unit will be available. The sale terms should describe the agreed collection condition. The transporter's role should begin from that stated condition, with handling information supplied by the appropriate specialist.
A vague allowance for “all removal” makes it hard to compare offers. It also makes it easy for two parties to assume the other has booked the specialist.
Choose the lot around the process
A complete cooling package may be easier for a buyer to assess than several unidentified components. Separate lots can make sense where each unit is independent and its specifications are clear. Neither approach is automatically better.
Check drying and dosing auxiliaries before treating every nearby cabinet as part of the chiller. For a unit serving several machines, use the shared factory services guide to establish what remains in use after the sale.
UK Auction Group can discuss how the chiller fits into a manufacturing equipment sale. Send the identity photographs, equipment boundary and proposed release date, with specialist work shown as a separate scope.
