Product Introduction

This compact package is documented for 40 gpm hot-water delivery using 100 gpm on the boiler-water side and a 6 gpm recirculation circuit. A single- or double-wall exchanger can be selected to separate the heating loop from the delivered water. Factory packaging combines the exchanger, controls and circulation components for small clean facilities where field-built hot-water stations would add coordination time.

Key Features

Compact instantaneous package

The skid heats flow on demand without a large local storage vessel.

Loop separation

A heat exchanger isolates boiler water from the clean-side distribution circuit.

Recirculation support

The 6 gpm return circuit maintains temperature at remote use points during low draw.

Technical Parameters

Hot-Water Flow	40 gpm
Boiler-Water Flow	100 gpm
Recirculation Flow	6 gpm
Heat Exchanger	Single or double wall
Package Type	Water-to-water instantaneous heater
Temperature Control	Electronic packaged control
Pumps	Matched primary and recirculation duties
Connections	Sized to selected flow and piping code
Primary Scale	Small facility hot-water station
Customization	Available based on the intended application and operating environment.

Applications

For small clean-facility wash points, equipment hot water and controlled process or sanitation distribution.

Solutions for Your Application

Delivered temperature drops during simultaneous peak use.Confirm the 40 gpm diversity, boiler-water temperature and exchanger approach before final sizing.

A single-wall exchanger is unsuitable for the clean-side water risk category.Select double-wall separation where the applicable water-quality or cross-contamination requirement calls for it.

Available Options

Specify supply temperature, exchanger wall type, boiler conditions, pumps, recirculation setpoint, materials, valves and controls.
