Cryogenic coolants pose certain health risks that are easily tolerated but important to consider.
To help you in minimizing this risk, all Sigma Systems chambers and platforms are provided with exhaust ports which can be connected to external exhaust systems. If ventilation is a problem, consider using a mechanically refrigerated chamber or platform. Mechanically refrigerated systems normally provide cooling by exchanging heat with the air. In a closed room, heat introduced by a refrigeration system will add to room heat and may tax the room air conditioning system. A simple solution can often be using water cooled mechanical refrigeration.
