ESS Series


Available in both reach-in or cart-based versions, the ESS Series allows highly accelerated product temperature change rates through high air velocity conditioning.

Weiss Technik has developed standard models that feature either our patented horizontal or vertical air flow, as different testing needs dictate that different temperature ranges, as well as change rate capabilities be readily available.

Weiss Technik will equip your system with single-stage, cascade, twin-screw, LN2 boost, or LN2 cooled refrigeration systems, as well as the powerful Weiss Technik Controller/Programmer—all standard. By utilizing Quick Draw, we ensure that your product reaches set point as quickly as possible to reduce cycle times.
