Cooling Load Calculations

Engineering Enquiry Data Sheet For Cooling Load Calculations

This information is used to calculate the amount of heat being added or removed from a room or product in a given time period.
When filling out the information remember that our equipment selections will be based on your information and on our knowledge of what is normal for this industry.
Be realistic about the amounts of product being processed, and the temperatures that product both enters the process and must achieve .
Be especially mindful of the time required to carry out the heat transfer.
Twice as fast cost twice as much to install and will cost more in power !
If you cannot answer every question answer the ones you can and will use our experience to fill in the gaps .
