Here is a briefing on three ways to save water using steam sterilizers.
1. One way to save water for a vacuum steam sterilizer is by using a closed cooling loop for the vacuum pump. In this method :
- The vaccum steam sterilizer will be equipped with a closed loop to cool the operation of the vacuum pump.
- The filling and level control of the loop will be done with “cold water“.
- Cooling of the loop and of the condenser between chamber and vacuum pump will be done with chilled water.
This method saves on average 300 liters of cold water per batch.
2. Another method that can be used for a vacuum steam or a steam-air sterilizer is a closed loop for jacket cooling or internal heat exchanger cooling. In this method:
- The equipment consists of a buffer tank with a certain volume, level controlled, a chilled water cooled plate heat exchanger, a circulating pump and the required pipe work system valves.
- All required control devices for a full automatic operation are included.
- The required equipment will be installed in the maintenance area of the autoclave.
Depending on sterilizer size, this method could save >1000l/h saving depending on the size.
3. Another method that can be used for a vacuum steam or a steam-air sterilizer Use of a plate heat exchanger instead of spray water condenser in the downstream line. In this method:
- The line is equipped with a plate heat exchanger. The plate heat exchanger is connected to a closed chilled water loop.
Depending on sterilizer size, this method could save >300l/h saving depending on the size.
