Offers many significant safety and maintenance advantages over our competitions’ hot water jacket systems.

One of ETC’s most premier innovations is the use of our chamber jacket heating system. ETC utilizes a hot air jacket chamber instead of a hot water jacket chamber heating system. The application of this unique design approach offers many significant safety and maintenance advantages over our competitions hot water jacket systems.
The hot air, closed loop heating system is designed to uniformly blanket the chamber and doors to maximize heating efficiency and temperature uniformity to meet the requirements of ISO standard 11135. This system achieves a temperature uniformity of +/- 3 degrees C of the pre-programmed control set point and gets there in less than three hours from an ambient room temperature of 21 degrees C.

  • By the utilization of heated air instead of a water-jacketed system, substantial savings are achieved in energy costs throughout the lifecycle of the sterilizer. Depending on the system design and the size of the chamber, the amount of energy required to heat and maintain the temperature of the water in a hot water jacket system alone, exceeds that of the product load.
  • A dry, hot air jacket heating system eliminates the corrosion and other maintenance concerns associated with water-jacketed systems.
  • Hot water jacket systems require additives that must be constantly monitored and balanced to slow down corrosion, and impose maintenance requirements that add to life-cycle operating costs.
  • Small leaks that may develop over time in a hot air heated system are not detrimental to the performance of the sterilizer temperature control and are easily repaired. Water leaks create operation and temperature performance problems, as well as maintenance hazards. Seals on such items as water pumps must also be constantly checked and replaced regularly, increasing maintenance costs and downtime.
  • ETC’s hot air jacketed systems are inherently lighter than equivalent water-jacketed systems and this enhances heating and cooling distribution. Additionally, because of their reduced weight, they are more easily manipulated for rigging and installation. Shipping costs are also reduced due to a lighter weight chamber.
