Product Introduction

The 920 kW package expands vessel diameter to 24 in and uses forty-six electric elements. A 6 in flanged outlet and up to 680 gpm documented flow distinguish its hydraulic hardware from the 280 kW model. The medium unit suits pharmaceutical or electronics facilities with several heating coils, provided electrical distribution, pump head and element staging are coordinated with the actual diversity of the hot-water load.

Key Features

Central plant capacity

The larger vessel and element bank serve multiple AHU coils from one electric hot-water source.

High-flow connections

A 6 in flanged outlet supports the documented medium-plant circulation rate.

Sequenced electric output

Forty-six elements provide multiple control steps for varying facility demand.

Applications

For medium pharmaceutical, electronics and controlled-production buildings with centralized hot-water heating and reheat demand.

Solutions for Your Application

Demand steps cause large electrical peaks when too many elements energize together.Use staged sequencing and demand limits coordinated with the facility electrical system.

A 680 gpm pump selection creates excessive velocity at part load.Select variable flow, bypass and minimum boiler circulation from the real coil diversity and vessel requirements.

Available Options

Specify supply voltage, staging, outlet arrangement, water temperature, pumps, expansion vessel, safety controls and communication interface.
