The Federal Bureau of Prisons (FBOP), FCC Pollock located at 1000 Airbase Road, Pollock, Louisiana intends to make a single award to a responsible entity that will provide all necessary equipment, materials, and incidentals to replace our existing hot water generators with Hot Water to Hot Water Plate Heat Exchanger System. The new units shall provide a a minimum the same water flow and recovery rates as from the 4 Lochinvar Hot Water Generator Units being replaced .

All manufacturers' recommendations will be implemented to achieve performance goals.

The 4 existing tanks in Fox Unit (Fl, F2, F3, F4) are:

(4) Lochinvar Hot Water Generator 504 gallon tanks - Model GVG0504JR-5-6-6956, 150 degree boiler water, 504 GAL storage capacity. Boiler Hot Water Inlet Temp 150 degree 2.5" NPT 114 GPM flow, Boiler Water Outlet 2.5" NPT.

Domestic Cold Water Inlet Size 3" NPT and Outlet 2" NPT. 120 voltage is onsite . Domestic Side Water Pressure is 50-60 psi coming into each Housing Unit.

Required Equipment Description:

2 Each - Double Wall Stainless Steel Plate Heat Exchanger, Hot Water to Hot Water Type Each Plate Heat Exchanger will produce min 38 GPM of Domestic Hot Water heated from 40F to 140F when supplied with 57-114 GPM Boiler Water at 140-160F before control valve . Typical Pressure drops between 3-8 psi. Specifications, Installation Drawings, Operation, Maintenance and Service Manuals must be included.

Digital Control Panel 4.3 HMI Touch Screen with BACnet or Modbus IP Connections with Set Point up to 180F. The controller shall be feed forward temperature sensing. Digital Control Panel power requirement is 120/240 VAC.
