BioUltra, made in Denmark, was BioLine's first ultra-low temperature freezer. The UL570 operates at −60…−86 °C for storing important biological materials and offers 530 litres of net space. These temperatures come from a bottom-mounted cascade refrigeration system using R290 and R170.
The cabinet combines vacuum-insulated panels with 70 mm of HFC- and CFC-free cyclopentane insulation. Behind the securely closing outer door are two insulated inner doors as standard, which limit temperature swings during opening. Inside are one fixed and four adjustable shelves, an access port for additional sensors and an E-sensor that simulates the core temperature of the stored product.
The MPC controller logs temperatures, gives visual and audible alarms and records the length of power cuts. Energy use 10.5 kWh per 24 h, noise 46.5 dBA, ambient range +10…+35 °C. Dimensions 856 × 979 × 1986/1996 mm, interior 623 × 601 × 1472 mm, gross volume 570 litres, net weight 257 kg.
Door hinging is chosen when ordering.
