Fresh-air heat recovery
Plate, rotary wheel or heat pipe sections in the air handling unit, so the exhaust air pre-cools or pre-heats the fresh air.
Heat Recovery Units
A heat recovery unit takes heat a building or plant already throws away, in exhaust air or hot process water, and passes it to the air or water coming in. MHM Engineering selects, supplies and installs MHM heat recovery units on air handling units and process lines, sized from temperatures and flows measured at your site.
Types
What this service covers
Run-around coil systems
Two coils joined by a pumped water loop, for when the supply and exhaust ducts are far apart or the two air streams must never meet.
Process heat exchangers
Plate and shell-and-tube exchangers that move heat from hot effluent or cooling water into incoming process water.

Highlights
Why plants choose MHM
Measured before sizing
Supply, exhaust and process temperatures and flows are read on site before a unit is chosen.
Fits the plant you have
Sections and exchangers are added to existing air handling units and pipe lines where space and pressure drop allow.
Streams kept apart
Where two air or water streams must not mix, a run-around loop or a separating exchanger keeps them apart.
