Direct steam injection pasteurizers and warmers can generally be converted at a reasonable energy payback to return condensate to the boiler. What's so big about condensate?
- It's new water and effluent cost that can be avoided
- It's already been treated with boiler chemicals
- (Most importantly) it has heat.
Existing direct steam pasteurizers and warmers can generally be converted to coils, or a single heat exchanger to Hot Water with a fantastic energy savings.
