The Model RCAV is a short, conditioned-air vestibule for freezer to outer room conditions that span large temperature differentials up to 100 degrees with average doorway traffic and limited floor space around the door.

It significantly reduces refrigeration load while preventing frost, ice and wetness at the doorway. It consists of two high speed rollup doors, and a heated horizontal, recirculatory air curtain between the doors. It is equipped with a PLC or Solid State automated control, to regulate the amount of air and heat required.

The Model ECAV consists of two fast-acting strip doors that create a vestibule for conditioning air and an electrically or hot-gas heated anti-frost air-conditioning (AFC) section with automatic temperature control.

The ECAV is designed for medium to light-traffic freezers and high humidity situations.

The Model 3CAV is primarily used between rooms with extreme temperature differences and very high traffic.

The frost elimination cycle is similar to the Model DCAV but the additional vestibule improves efficiency as well as increases the model's temperature range applicability. 

The Model 3CAV automatically adjusts as conditions change to optimize performance and reduce energy consumption.

With the use of HCR sensors and software, Model 3CAV can be integrated into a facility's refrigeration control and monitoring system.  This allows both remote monitoring and remote adjusting of the HCR equipment.

A small conditioned air vestibule with touch opening capability.
