They manufacture navigation devices for land, road, trail and water and they needed to evaluate circuit boards @ various temperatures (-30 °C to -40 °C, no or minimal heat load, room temperature ambient) and on recommendation of a person who joined them from a controls company and had been using the solid state cold plate AHP-1200CAS. The system required the cold plate, cascade, cascade control and tapped plate. The tapped plate is built into the cold plate in place of a smooth plate surface to attach to the cascade plate.
The cascade control facilitates power and temperature control to the cascade. The system also included an acrylic cover and insulation block. They received the system and liked how it is built.
