New Dual Heat Exchanger from Allmand 

Allmand's new Maxi-Heat MH500iQ dual heat exchangers produce a maximum of 1,000,000 combined BTUs and can be operated independently depending on heating requirements.  Standard 16-inch heater outlet flanges and optional flexible ducting provide a wide variety of heat distribution options.

By adjusting the power with the double-nozzle feature and the electronic control, it reaches the target temperature and avoids start/stop action, which can be hard on equipment. The iQ analyzer detects environmental temperature and pressure, suggests the correct burner setting and automatically configures the nozzle, eliminating the need to change the nozzle as the altitude changes.  

Dents on the wall of the heat exchanger increase turbulence and heat exchange, improving efficiency. A probe at the end of the heat exchanger measures the heated temperature and transmits to the iQ, which eliminates the thermoswitch. An airflow chamber between the combustion chamber and the exterior cools the external surface, increasing safety and efficiency.

For easier maintenance, most of the electrical parts have an easy unplug function and do not require hard wiring. Removable bolted windows at the end of the chamber allow easy access for cleaning and re-assembly. The MCS500iQ is robotically welded, reducing the risk of failures and improving quality.  

Its 250-gallon fuel tank capacity provides more than 30 hours of continuous operation.  CAT or optional Isuzu liquid-cooled 1800-rpm diesel engine with 9 kW transformer-regulated generator provides power to operate heater blowers and safety systems.

An optional combustible gas detection system powers down the unit and operates a strobe alarm before gas accumulation approaches potentially explosive levels, providing increased safety when used near well heads in gas or oil fields.
