VWR Vwr Ad 15l Rfg/htg -40 240v Unit EA. The water circulating system circulates cooling water throughout the total volume which is necessary to maintain a consistent temperature. The two heater elements are located in the lower section of the chamber to prevent heat build up. The plates feature steel back plates and a unique lid which admits a large volume of water and conserves the heat. Users can regulate the humidity with the change of the hose clamp. Additionally controls built into the lid provide the ability to modulate the humidity. This allows the user to better control the humidity in their chambers. The varied speed of the heating and cooling systems provide the flexibility needed for the widest range of applications.
