Product Overview
The 06TSM155 HVAC screw compressor is engineered for high-capacity commercial HVAC chillers, process cooling, and medium-temperature refrigeration systems. This 75 HP unit delivers optimal performance with R22, R404A, and R507 refrigerants.
Medium-Temperature Twin-Screw Design & Economizer Circuit
Featuring patented twin-screw rotor profile geometry, this compressor reduces clearance volume and gas recirculation losses. The integrated economizer circuit with 1-3/8 in. connection provides subcooling capability to maximize cooling capacity and system COP.
Stepless 25%-100% Capacity Modulation
Maintain precise fluid temperature control with smooth, stepless capacity adjustment from 25% to 100%. Combined with partial-load volume ratio optimization, this prevents over-compression penalties and significantly lowers seasonal energy consumption.
Heavy-Duty Mechanical Engineering & Built-in Protection
Designed for long-term continuous operation without external oil pump, featuring high-load SKF or NSK rolling bearings and reinforced axial thrust bearing assembly. Internal protective devices include:
- Internal Check Valve: Prevents reverse rotor rotation during system shutdown
- Safety Relief Valve: Prevents internal overpressurization during abnormal operation
- External Oil Filter: Allows fast inspection and replacement during maintenance
- Motor Thermal Protection: Integrated NTC thermistor sensors monitor winding temperatures
Global Electrical Compatibility & Factory Testing
Every unit undergoes 100% factory running tests and 33-point quality control inspection. The robust motor supports Star-Delta and DOL starting configurations across major 50Hz and 60Hz commercial supply voltages (200V-460V).
Included & Optional Accessories
Standard Accessories: Junction Box, Oil System Assembly, Motor Protection Module, Capacity Control Valve, Service Stop Valves
Optional Accessories: Oil Separator, Mounting Flanges, Economizer Kit, Oil Cooler, High-Temperature Expansion Valve, Kriwan Protection Module, Paragon Control Board
