1. How do I determine which type of Haskris system is the best solution for my specific requirements?

Contact Haskris and one of our application engineers will be glad to work with you.

2. How much heat is added to a room containing an air-cooled mechanically refrigerated water recirculator?

The same amount of heat that is removed from the instrument, plus an additional 30% for the motor heat of the Haskris recirculator. Alternately, the heat can be calculated by taking the horsepower of the refrigeration compressor, multiplying it by a total heat rejection factor of 15,600 and by the fraction of the compressor's running time per hour.
Example: Model R075, 3/4 HP and 40 minutes/hour total running time of refrigeration compressor
(.75) x (15,600) x (40/60) = 7,800 BTU/hr
Note: The compressor on a refrigerated recirculator furnished with Option (G) or (H) will run continuously; therefore, the compressor running time multiplier is 1.0.

3. If we prefer not to have the heat from a refrigerated recirculator expelled into the room, what are the alternatives?

Contact Haskris and one of our application engineers will be glad to review the alternatives with you.

4. How much Building Water is consumed by Option (C), Water-cooled Condenser?

5. Can a Haskris system be installed outdoors?

Yes, Haskris systems can be installed outdoors when they are designed appropriately. Contact Haskris and one of our application engineers will be glad to work with you to design an outdoor rated unit to meet your site requirements.

6. If we decide to locate the recirculator on a floor above or below the instrument, can the standard water recirculating pump handle the additional resistance?

Yes, the additional pressure required is only needed to overcome the friction in the piping. The resistance due to pumping water against gravity is cancelled by the "free fall" of the water on the return side.

7. If we need additional water pressure to the equipment being cooled, is this capability already built into the system?

Yes, go to our Water Pressure Bypass/Relief Valve information document to learn about the operation of the adjustable bypass relief valve furnished with our products. Please keep in mind any pressure adjustment must have the prior approval of the manufacturer of the equipment being cooled.

8. Where can I get the most complete information on the operation of a specific recirculator?

Contact Haskris and one of our application engineers will be glad to work with you.

9. If a challenging electrical or mechanical problem develops, where do I turn?

Contact Haskris and one of our application engineers will be glad to work with you. Most mechanical problems can be analyzed and repaired by a competent local refrigeration contractor; it would be helpful to have the unit instruction manual available.

10. How often should I change the water in my water recirculator?

When the unit is new we recommend you inspect the reservoir at least once a month to make sure the water is clear, has a neutral pH, and there is no accumulation of debris. Clean the tank, as needed. The frequency of required maintenance will be determined by experience over time. Go to our Water Treatment for Biological Growth document for further information.

11. If we need to confirm the electrical requirements (voltage, phase, hertz, amperage, etc.) of the Haskris system, what do you suggest?

Refer to the front sheet of the Instruction Manual, or the system nameplate label for newer Haskris units. If the electrical requirements cannot be located, please contact Haskris.

12. There is no (or low) pump flow. I'm not sure if I have a pump problem or an external restriction. How do I troubleshoot this problem?

Restrictions in pumping systems are often the source of flow alarms in cooling applications. A supply filter, shut or stuck valve, kinked hose, etc. will create a resistance to flow and increase the overall system pressure. If the pressure increases enough the bypass relief valve (standard in Haskris design) will open and divert the flow of water back to the reservoir, protecting the application and the pump motor.

The best way to troubleshoot this type of problem is to isolate the chiller from the rest of the pumping circuit. This can easily be done by using a short piece of tubing connected to the pump Supply and Return on the Haskris unit; this "short circuits' the connected piping and application. If an external restriction exists, the operating pressure of the system will drop (usually less than 20 psi) and the flow rate will increase; this is visible on the flow meter if Option (A) Flow Meter is furnished.

If you suspect a pump issue and your system is furnished with a positive displacement pump, refer to our Positive Displacement Pump Troubleshooting for more information. Contact Haskris if the pump flow issue persists.

13. How can I get a copy of the manual for my Haskris chiller?

Contact Haskris. Please have the serial number of the chiller available as all of our systems are built to specification. One of our engineers will make sure you get the technical documentation you need to solve your problem, whether it's to update your company files or to troubleshoot an existing situation.

14. The cooling water temperature to my application is abnormally high? What do I do?

Contact Haskris. Please have the serial number of the chiller available as all of our systems are built to specification. One of our application engineers will be glad to work with you.

15. If the copper lines inside the reservoir develop a blue-green scale, is this a matter of concern?

No, this scale is a basic cupric carbonate that forms in all systems over time. It is only a problem if it accumulates to the point where it flakes off and clogs the pump suction strainer. If this happens, contact Haskris and we will advise you what to do.
