Cascade Propane (R290)/ Isobutane (R600a) Heat Pump
Cascade R290-R600a Heat Pumps
The Natural Refrigerant Cascade Propane (R290)- Isobutane (R600a) Heat Pump from the Budzar Green line of Budzar Industries are ideal for applications requiring simultaneous heating and cooling.
The significant temperature lift this system provides by utilizing the mid-temperature Propane (R290) refrigerant and the high temperature Isobutane (R600a) refrigerant, allowing high efficiency. With two refrigerant circuits, it reduces energy consumption and the lessens the environmental impact by channeling the cooling generated to your other process, eliminating the need for separate heating and cooling equipment.
Budzar Green Cascade R290-R600a Heat Pumps may be customized to meet your requirements. Options include:
- Number of circuits
- Remote Monitoring Capability
- Fluid Cooler System
- Glycol Loop
- Pumping Station
- Screen Size
Features of these natural refrigerant heat pumps include a shared cascade Brazed Plate Shell & Tube exchanger that serves as the condenser on the Propane (R290) circuit and the evaporator on the Isobutane (R600a) circuit. The system also includes Digital PLC Control & Display.
Other Propane (R290) features included:
- Cooling Output down to -33°F
- Heating Output Range 65°F to 135°F
- Modular design 1 ton to unlimited
- Simultaneous temperature control
- Refrigeration Screw Compressor
- Electronic Expansion Valves
- Guaranteed-off timer(s) to defeat compressor short cycling
Other Isobutane (R600a) features included:
- Cooling Output down to 25°F
- Heating Output Range 110°F to 200°F
- Modular design 1 ton to unlimited
- Simultaneous temperature control
- Compact Screw Compressor
- Electronic Expansion Valves
- Guaranteed-off timer(s) to defeat compressor short cycling
Standard Cascade Propane (R290) Isobutane (R600a) Heat Pumps are designed as a Water Sourced System. Upgrade to an Air Sourced design, which includes high pressure receivers for low ambient conditions and separate Brazed Plate Stainless Steel Evaporators.
