The 4VAP is an oxalic acid evaporator with digitally controlled evaporation temperature designed for commercial or multi-hive beekeepers. We make this vaporizer from 2016.

The stainless steel chamber of the 4VAP vaporizer is heated by a heating element to 230V. The temperature is controlled by a programmable thermostat and is factory preset to 220 ° C.

We also offer a version with a copper evaporation chamber - copper is a better conductor of heat.

The evaporator includes two teflon caps, which also serve as an acid bowl. The evaporated acid smoke is sublimed from the chamber into the beehive. The evaporation time of 2 g of acid is about 30 seconds.

This vaporizer is designed for use in locations where 230V power is available.
