Haskris works closely with its customers to design chillers that solve problems. Click the arrows below to read about how Haskris has provided solutions to difficult situations.

MRI Equipment OEM

Problem:
The OEM customer was experiencing chiller reliability problems and unresponsive support. They needed a better solution for their new generation of MRI equipment.

Solution:

Haskris developed a robust outdoor chiller design to withstand the harshest weather elements and wrapped the product offering with a tailored support program that included no-load and full-load start-up services, scheduled preventative maintenance services, on-call tech support and after-hours service availability. The enhanced offering eliminated chiller downtime during scanning hours and allowed the OEM to meet their contractual obligations towards guaranteed uptime.

X-ray Equipment OEM

Problem:
The customer’s equipment is used in heavy industrial applications with harsh environmental conditions, including heavy airborne dust and ambient air temps that range from 20F to 120F. Process water is not available at the customer sites, so only air cooled chillers can be used. And the OEM equipment requires precision water temperature control of +/-0.1C. For over 10 years the OEM lived with constant chiller failures because they could not find a proper chiller design. The OEM switched chiller suppliers 3 times before finally learning about Haskris.

Solution:
Haskris developed a proprietary temperature control system to meet the precision requirements of the application and designed a special air cooled refrigeration system that could withstand the extreme air temperatures and dirty conditions. The solution has been a huge success, virtually eliminating chiller related downtime at the end user production facilities.

Inspection Equipment Manufacturer

Problem:
The OEM equipment had two heat sources, each cooled by a dedicated water circuit. Each circuit required a different water temperature, and so the OEM was using two water chillers. This was expensive and the two chillers consumed a lot of floor space.

Solution:
Haskris developed a dual-temperature chiller that is capable of supplying two different water temperatures from a single reservoir of water. This design cut the chiller cost in half and conserves valuable floor space at the installation sites.

Semi-Conductor Equipment Manufacturer

Problem:
The OEM equipment is installed in clean rooms with the chiller located 30ft. below in a sub-fab. The application requires precision temperature control of +/-0.05C, and exceptionally low flow rates that must be pumped against a significant head pressure. The OEM experienced chronic chiller failures, primarily in the pumping system. They discovered that an unidentified contaminant was getting into the water stream and ultimately clogging the system and destroying the water pumps. The OEM worked with 3 other chiller suppliers with no improvement before learning about Haskris.

Solution:
Haskris worked in partnership with the OEM, conducting extensive testing on the equipment to reproduce the problem, ultimately identifying what the contaminant substance was and where it was coming from. From there Haskris developed a solution that included special materials of construction, specialized flow controls and a customized mechanical water treatment package that controlled water chemistry.

Additionally, the solution was designed into a cabinet size identical to the existing supplier’s cabinet so that field retrofits would be seamless. The chiller was also designed with universal electrical characteristics so that one chiller configuration could be used in both 50Hz and 60Hz countries.

Magnetic Imaging Equipment Manufacturer

Problem:
1. The OEM equipment had a significant heat load of 10kW, which creates problems for their customers since many cannot tolerate that level of heat dissipation in their facilities.

2. The OEM did not have chiller expertise in-house and were becoming frustrated at the amount of internal resources they had to spend dealing with chiller issues.

Solution:
Haskris proposed a unique partnership arrangement to work directly with the OEM’s end user customers to profile the installation sites and ultimately design tailored chiller configurations that would both optimally serve the OEM equipment and end user facility.

Today the OEM is relieved to have a trusted partner in Haskris to take on full responsibility of their chiller program. The end users are better served working directly with Haskris by taking advantage of our flexible design capabilities to develop solutions that minimize the effects of heat and noise into their facilities.

Analytical Equipment OEM

Problem:
The OEM was experiencing reliability and lead time problems with their existing chiller supplier. They needed to make a change, and they had a critical customer who needed a chiller within 3 days.

Solution:
Haskris received the specifications of the application on a Thursday and submitted a proposal the same day. The custom chiller was ordered on Friday and needed to be shipped on Monday. Haskris gathered a small team of people to work through the weekend to build and test the chiller. The chiller was drop shipped to the end user on Monday and installed on Tuesday. Mission accomplished! And a new OEM relationship has begun.

Environmentally Controlled Test Chamber OEM

Problem:
The customer historically built their own on-board heat exchanger assemblies designed to circulate highly deionized water to cool a specialized light/heat source inside their test chambers. The heat exchanger assembly was designed to be cooled by an external source of tap water, which created a high operating cost for the end user. In many cases, the end user was prohibited by law to use tap water for process cooling.

Solution:
Haskris re-designed the client’s heat exchanger assembly to include modern technology for efficient heat transfer, resulting in a significant reduction in the use of tap water. Additionally, Haskris designed an air cooled version of the assembly for customers who were prohibited by law to use tap water.
