Economizers & Heat Exchangers

Best Performance. Fastest Payback.

ENERVEX’s VHX Economizer is a Waste Heat to Water (WHW) heat exchanger that converts exhaust waste heat into hot water.

The VHX is designed around our modular hybrid micro-channel/plate heat exchanger modules that are extremely efficient, yet compact. It is extremely versatile and can serve dual uses such as supplying hot water to a Waste Heat to Power (WHP) system while simultaneously supplying hot water to a separate application. Compared by physical size it produces 200% to 300% more savings than a traditional economizer.

In many applications and processes, as much as 20 to 50% of the energy consumed is ultimately lost via waste heat in streams of hot exhaust gases or from heated product streams.

Where can the waste heat be used?

A Waste Heat to Water (WHW) system can generate hot process water, potable hot water, and hot water for building heating. But it is also an essential component in most WHP systems. We design and supply packaged WHW to WHP solutions.

A WHW system can reduce fuel consumption by 5-10% and typically pays for itself in less than two years.

Taking advantage of waste heat is not only profitable, but practical. The VHX solutions can be an essential part of a company’s Environmental, social, and governance (ESG) strategy and initiatives.

How Much Can I Save?

Input Form: Process Air Application  Input Form: Boiler Application

VHX Economizer Single Row—flue gas economizer

A versatile and efficient single-row flue gas economizer for applications with tight space. Can help you conserve energy and save 10+% on fuel annually.

VHX Economizer Double Row—two-stage flue gas economizer

A highly versatile and efficient double-row flue gas economizer that can help you conserve energy and save 10+% on fuel annually.

HRC80 Economizer Controller—monitors inlet/outlet water and flue temperatures

A totally integrated heat recovery control system that monitors inlet and outlet water and flue gas temperatures to maintain the outlet water temperature you need, while maximizing heat waste recovery and efficiency.

HMM Heat-Module Manifold—used alongside economizers to connect the heating on the supply and return sides

The HMM heat-module manifolds are used in conjunction with the VHX Economizers. They are used to connect the heating on the supply and return sides.
