Pump Station is part of a medium temperature secondary refrigeration system that uses water and a 30-35% propylene glycol mixture to cool the refrigeration loads. A central direct expansion system with a low HFC charge is used to cool the glycol mixture. 

Standard Features and Benefits:

• Up to 70% lower refrigerant charge than a central direct expansion system
• Up to 50% carbon footprint reduction
• Leak rates as low as 10%
• Up to 10% installed cost reduction
• More cost-effective equipment sizing due to pumps on a separate assembly from the heat exchangers, which are mounted on the rack
• Glycol pumps sized according to the flow rate
• Heat exchangers can be sized independently by the loads
• Control inputs match rack control brands
• Accepts multiple brands of pumps and expansion valves
• Increased reliability due to fewer components
• Easy to install and service
