Define the compressor, then the refrigeration system
Snowman connects compressor technology with industrial refrigeration, cold-chain systems and ice-making equipment. Its company history dates the business to March 2000 and its Shenzhen listing to December 2011. The group identifies SRM and RefComp as its compressor brands, while SNOWKEY covers ice-making equipment.
That portfolio gives a buyer several possible supply boundaries: a compressor, an assembled refrigeration unit or a wider cooling/ice-making system. Start by deciding which boundary your enquiry covers, then name the compressor family and thermal duty.
Open drive or semi-hermetic: what changes for the buyer?
SRM · external drive integration
Open-type single-stage screw
The manufacturer lists six series, from SRM-12 through SRM-41, with 19 models. Its open construction requires a drive arrangement to be agreed as part of the supply.
- Match motor, coupling, speed and alignment responsibilities.
- Define oil-system, cooling and capacity-control scope.
- Check seal service access and the proposed arrangement drawing.
The SRM page describes adjustable built-in volume ratio and continuous capacity control. Request the exact model's selection and control arrangement for your temperature lift and load profile.

RefComp · integrated motor construction
SW3H or SW3L semi-hermetic screw
SW3H addresses medium/high-temperature refrigeration; SW3L addresses low-temperature duties. The cited SW3 family has 28 models. The photo is an SW3H example.
- Match the application subgroup before motor power.
- Confirm suction-gas motor cooling and operating envelope.
- Specify stepped or continuous capacity-control configuration.
The catalogue describes temperature, phase-loss and reverse-rotation protection and an integrated suction filter. Obtain the model's electrical/protection requirements and integration instructions.

SRM single-stage open screw
- Family displacement
- 265–10,000 m³/h at 2,960 rpm
- Listed refrigerants
- R717, R404A, R507A
- Catalogue construction
- 5+7 rotor profile · ductile-iron body
- Published control description
- 10% to full-load continuous adjustment · adjustable Vi
The cited 2.8 MPa body working-pressure figure is a mechanical reference. It is not the evaporating/condensing operating point or a cooling-capacity rating.
RefComp SW3 semi-hermetic screw
- Family displacement
- 118–700 m³/h at 2,960 rpm
- Family motor range
- 30–240 HP
- Listed refrigerants
- R507A, R404A
- Application split
- SW3H medium/high temperature · SW3L low temperature
These are range-wide figures. Do not pair the lowest or highest motor rating with a displacement endpoint without the exact model table and thermal selection.
Different projects need different starting information
New cold store
Establish the refrigeration load and room/product temperatures before selecting a compressor. Include operating schedule, pull-down requirement, heat-rejection conditions and redundancy. Identify whether the supplier should select a unit or only quote an already selected compressor.
Industrial process cooling
State the fluid or process to be cooled, inlet/outlet temperatures, flow and load range. Define refrigerant and condenser conditions where available. Clarify whether heat exchangers, oil system, controls and electrical panel belong in the offer.
Replacement compressor
Send the old nameplate, model suffix, refrigerant, measured conditions and available installation space. For SRM include external drive/coupling details; for SW3 include voltage, protection and control arrangement. Similar displacement alone does not prove interchangeability.
Approve the supply in three stages
Confirm the selection
Request a current model selection with cooling output, absorbed power and permitted envelope at the same conditions. Include minimum load and the chosen capacity-control method.
Confirm the integration
Approve arrangement, connections, electrical/protection requirements, oil and cooling scope. For an open-drive machine, assign motor/coupling and alignment work. Agree which components are included and which are site-supplied.
Confirm release and support
Agree model/origin/nameplate records, applicable product documentation, inspection requirements and operating instructions. Identify commissioning responsibility, service-part numbers and destination support in the quotation.
Prepare a Snowman enquiry with a clear boundary
Compressor-only enquiry
Send SRM or RefComp family and model, refrigerant, evaporating/condensing conditions, speed and voltage/frequency. Specify capacity control, replacement constraints and required documentation.
Packaged refrigeration enquiry
Add the thermal load, process/room conditions, heat-rejection utilities, load schedule, redundancy and installation location. Request an itemised boundary covering compressor, drive, oil system, heat exchangers, controls, testing and startup.
Compare equivalent offers
Keep refrigerant and selection conditions consistent across quotations. Compare actual selected cooling output and input power, supply scope and acceptance obligations rather than the family displacement headline.
Questions before choosing SRM or RefComp
Does an SRM-12 have the whole 265–10,000 m³/h range?
No. That range covers six SRM series and 19 models at 2,960 rpm. Obtain the exact model's displacement and refrigeration selection before using either endpoint.
Is SW3H the correct option for a low-temperature duty?
The published split places SW3H in medium/high-temperature applications and SW3L in low-temperature applications. Select the named model against the required refrigerant and operating envelope.
Is the 2.8 MPa body figure my system's operating pressure?
It is the catalogue body working-pressure reference. The refrigeration operating point and design requirements must be established for the selected refrigerant and system, including applicable pressure-equipment requirements.
Does ordering a compressor include a refrigeration unit?
Agree the boundary explicitly. A bare compressor entry does not establish inclusion of the motor, oil system, heat exchangers, electrical controls, assembly or commissioning. Ask for an itemised offer.
