High Pressure

For high pressure applications, the GLYCOOL system can be equipped with components rated at 300 psig (2069 kPa).

9.3.1Dual Pump Package

The dual pump package features two full size glycol pumps, each capable of providing sufficient flow for system operation. A flow switch will sense the loss of flow, should the lead pump fail, and automat- ically command the standby pump to start. The complete system includes dual pump housing, pumps, lead-lag switch and flow switch (for field installation). The dual pump package provides redundancy, protecting against costly downtime in the computer room.

Quiet-Line Drycoolers

Quiet-Line Drycoolers can help your facility meet the strictest noise codes, and do so at less cost than traditional drycoolers with acoustical shielding.
