Ultra low temperature chest freezer Boreas

Laboratory space is valuable. Compared to traditional freezers, Telstar Boreas Ultra Low Temperature Freezers use ultra-thin vacuum insulation panels. With only 80 mm of insulation, they guarantee a much better insulation value than the 125 mm standard PU foam. A temperature of -86oC is guaranteed for an ambient up to +30oC. Furthermore thin insulation increases the storage capacity by up to 30%.

The Boreas chest series is available in three sizes; C370, C620 and C820 litres capacity to meet the needs of the customer looking for either a small footprint or a unit with a very large capacity. The height and depth off all Boreas units never changes, only the width does, ensuring any unit can pass through narrow doors.

The adoption of green gases puts the Boreas series ahead of upcoming regulations that will ban the use of the traditional mix of synthetic potent greenhouse gases normally used in ULTs.

Taking responsibility for the environment

Safety for your samples is paramount but why not be kind to the environment as well? Telstar has embraced this ideology and always uses ecological refrigerants in its freezers. Unlike the traditional used mixed synthetic potent greenhouse gases, Telstar is a pioneer in using 100% pure natural refrigerants, CFC, HCFC and HFC free. In addition the hydrocarbon systems used by Telstar are safety compliant in accordance with EN60335-2-24.

Low sound level and low power consumption

The Boreas green line only uses high quality and energy efficient compressors. Combined with the use of natural refrigerants it achieves a mix of low power consumption and noise levels, around 50 dB(A), in line with  NEN-EN-ISO 11202 requirements. 

Standard eye-level control

A reliable self-diagnostic monitoring and alarm system is positioned at eye level, far from dust and moisture. The bright liquid crystal digital display is clearly visible from afar. The most critical values (sample temperature, ambient temperature, and voltage) can be checked in a blink of an eye! 

User friendly access to your samples

No freezer is ever opened with empty hands. To facilitate single hand opening Telstar has developed an ergonomic door handle. This easy–grip handle helps to effortlessly open the door and firmly press the door closed.

A heated vacuum equalisation valve allows smooth frequent door openings.      

Flexible sample storage

As a standard the Boreas chest series are equipped with polystyrene inner sub lids to further limit heat dissipation when the units are opened. To ensure the highest quality standards, the inner chamber is entirely made of Stainless Steel. Telstar is the only manufacturer offering a complete Stainless Steel interior. This means not only Stainless Steel inside walls, but also the main door inner panel. 

Top class temperature performance

Telstar has developed a ultra-low temperature freezer with low power consumption, without making any compromises in cooling performance. The combination of ultimate temperature recovery times with very stable and uniform temperatures throughout the cabinet ensures top class performances. The package is completed by the VIP insulation which ensures slow temperature rise in case of power failure.
