INCREASED PRODUCTION

The speed and accuracy of production will increase as you maintain a constant and proper cooling temperature in your equipment. A chiller will reduce the number of rejected parts while increasing the number of parts produced per hour. You may ask yourself: "Does my equipment shut down during summer months?" -- "Are there periods where our rejection rate increases?" A COOLING TOWER may provide adequate cooling during winter months, but fail during the hotter periods of the year. A Water/Oil chiller will immediately eliminate this problem.

Why a Chiller?
 

for Equipment Protection -The most compelling reason for a chiller is the protection it provides to your valuable process equipment-- such as laser machines , spot welders, injection molding equipment, and other applications. A chiller commonly represents a small fraction of the cost of the processing equipment, yet it provides solid protection of your investment, 24 hours a day, 7 days a week for years and years to come.

Sizing a Chiller Correctly - calculate cooling load of Water chiller - how to size chillers


Simple instructions to Assure Proper Cooling The importance of selecting a correctly sized Water chiller cannot be downplayed. An undersized Water chiller will always be a problem-- never able to properly cool the process equipment. An oversize chiller will never be able to run at it's most efficient level. Specify the correct size chiller and enjoy years of continuous, efficient service. If you would like help, feel free to give us a call. We do this all the time.
To size a Water chiller properly you first need to calculate the delta T ( deg C)between the inlet and outlet water (the change in temperature), and the rate of flow in liters per minute (LPM). Measuring the delta T requires a thermocouple or thermometer. Check the water temperature of the water inlet line and the water outlet line, and subtract the numbers to compute how much heat the equipment is adding to the water.
To measure the flow rate of the water place a flow meter on the outlet line of your equipment. If one is not available, simply measure the time it takes for the outlet flow to fill a twenty Litre bucket, and then compute your Litre per minute (LPM) of flow.
Now that you have these two figures you need to calculate how many kcals (kilo calories of heat Units) your equipment dissipates. Here is the formula:
                    # kcals/ hour = (the weight of water) LPM x Temperature Difference (delta T)
Repeat this for all the equipment you have, and add up the total kcals.
Now that you have the kcals, lets compute the total Tons of cooling you need from a chiller.

                   1 Ton of cooling is 3000 kcals/hour so...
                   # Tons = (kcals/hr) / (3,000)
This is the minimum size unit you should need.please keep another 25-30 % margin for There may be other circumstances, like planning for expansion, that would lead you to buy a different size unit.
