direct contact heat reduce energy costs


Up to 100% fuel efficiency, flue gas temperatures as low as 50o F (10o)C

 Description
The PERCOMAX TM is a "DIRECT-CONTACT", natural gas fired, water heater which is designed to heat water to temperatures as high as 185°F (85°C).

 

Operation

In a PERCOMAX TM combustion occurs in a fully modulating, integrated gas burner. Cold water enters the unit at the top and is then uniformly distributed over the upper surface of a packing of stainless steel nodules which constitutes the heat transfer zone. The water percolates down through the packing where it comes in "direct-contact" with the rising, hot products of combustion. Both the sensible and latent heat contained in the gas are transferred to the water. The products of combustion are generated by a fully modulating, integrated, natural gas burner.

 

The heated water collecting at the bottom of the unit is then pumped directly to the process, or across a plate and frame heat exchanger to transfer its energy to a building heating loop or process fluid.

 

Construction

All wetted components and materials, including the unit's shell and the packing, are entirely fabricated of stainless steel, and are covered by a 5 year guarantee.

 

Applications

Domestic water heating, hydronic (space) heating, fresh air heating (via glycol loop), boiler make-up water pre-heating, and process water heating.

 

Capacities

The PERCOMAX TM is available in capacities varying from 1 to 50 million BTU/hr (300 to 15,000 kW). If you require greater capacity, contact SOFAME.

 

Advantages

•Very high efficiencies; up to 100% (based on HHV).

•Maximum flue gas temperatures no more than 10°F (5.5°C) greater than cold water temperature at inlet.

•Minimum maintenance required.

•Reduced emission of atmospheric pollutants.

•No supervision required (unit is not classed as a pressure vessel).

•Rapid unit start-up (instantaneous hot water production).

•Can be installed outside.
