Refrigeration & HVAC Components for Systems That Need the Right Part, Not Just a Similar Part
Refrigeration and HVAC components are the working pieces that control, protect, measure and move refrigerant or other system fluids. Sofia Cooltech Engineers supplies a broad range of these components for commercial refrigeration, cold rooms, cold storage, industrial cooling, process cooling and HVAC applications.
The range covers expansion valves, refrigeration valves, solenoid valves, pressure controls, temperature sensors, liquid-level controls, electronic controllers, heat exchangers, compressors and condensing units. These products are useful for new equipment requirements as well as component replacement, maintenance and system restoration work.
The important part of component supply is technical matching. Refrigerant, cooling capacity, pressure, temperature, connection size, electrical characteristics and the existing equipment all influence whether a component is suitable. Our approach is therefore to understand the application first and then identify the product category and specification that fit the system.
Need Help Identifying a Component?
Send the model number, part number, equipment nameplate or a clear photograph of the existing component. Including the refrigerant and equipment application makes the technical review much more useful.
