MPS Turns Up the Heat

Video overview of the Commander 3400 Heat Recovery System option.
Many areas of the globe experience stretches of extreme cold during the winter months. In fact, here in Minnesota, it’s not unusual to have several artic blasts that send temps to -25 degrees with wind chills approaching -50 below zero. This means MPS camera trailers must be able to withstand the cold and protect the battery packs and electronic components that power the entire system.

Any time the batteries reach a temperature level below 32°F they start to lose capacity and that capacity loss starts to negatively affect fuel efficiency and system reliability. If the batteries are allowed to freeze, this could permanently damage the batteries and shorten their life. The MPS Heat Recovery system option uses excess heat from the generator to warm the body enclosure and maintain the temperature of the batteries and electronic components for maximum reliability.

The MPStatus system uses temperature readings from the generator, body enclosure, rack enclosure, PCM Power Control Module, and ambient temperatures to control an actuator that opens or closes a vent door located in the airflow between the generator and the outside.

Left: View from the underside of the trailer showing the vent door and actuator that controls the heat flow from the generator (gas or diesel) and redirects that latent heat into the body enclosure.

When the body enclosure temperature falls below 30°F, the generator starts running and it quickly heats up the body enclosure to 100°F and maintains that temperature. This pumps heat into the high mass of the battery bank and surrounding components. Then when the generator isn’t running, the batteries expel that heat over time.
