Product Introduction

The medium package delivers 70 gpm of hot water from a documented 175 gpm boiler-side flow and uses an 11 gpm recirculation circuit. Its larger exchanger, pump duties and electronic temperature-control components distinguish it from the 40 gpm skid. The unit suits pharmaceutical sanitation and controlled-process systems that need stable distribution temperature under moderate simultaneous demand.

Key Features

Medium process capacity

The exchanger supports multiple wash or process users beyond the compact package range.

Packaged temperature control

Electronic control modulates the heating side to hold the selected hot-water outlet condition.

Larger return circulation

An 11 gpm loop reduces waiting time and temperature decay in a broader distribution network.

Technical Parameters

Hot-Water Flow	70 gpm
Boiler-Water Flow	175 gpm
Recirculation Flow	11 gpm
Heat Exchanger	Single or double wall by service
Temperature Control	Packaged electronic control
Package Type	Instantaneous water-to-water heater
Circulation	Dedicated boiler and return duties
Materials	Selected for water quality and sanitation
Primary Scale	Medium facility distribution
Customization	Available based on the intended application and operating environment.

Applications

For medium pharmaceutical sanitation loops, controlled production wash systems and facility hot-water distribution.

Solutions for Your Application

Control valve authority is poor because the boiler-side pressure varies widely.Coordinate the 175 gpm circuit, control-valve pressure drop and pump control across minimum and maximum load.

The 11 gpm recirculation flow cannot maintain remote loop temperature.Calculate actual distribution heat loss and adjust return pump duty or insulation before final selection.

Available Options

Confirm draw profile, temperatures, exchanger construction, water quality, pump heads, recirculation, skid materials and BMS connection.
