"We had been looking for a control valve on ammonia hot gas applications for transfer systems that could reduce hydraulic shock, provide low pressure drop and fit into our stainless piping program. The HANTEMP COBRA-NECK Stainless Steel Ball Valve with motorized control has been a perfect solution for this application. We can open the valve slowly and throttle the hot gas back to the system and eliminate hydraulic shock to the piping. The HANTEMP ball valve stainless steel design avoids having dissimilar material with our stainless steel piping, and our customer also has a corrosion free control valve. We have installed several HANTEMP COBRA-NECK ball valves and they are performing well." -Rick Watters, AMS Mechanical Systems Inc. Burr Ridge, IL |

"The HANTEMP SSBV 2½" Ball Valve with pneumatic actuator is working excellently in our application. The HANTEMP design has the ideal characteristics needed to function as a low pressure drop valve in our oil scrubber feed line." -Daniel Wu, Woodley Goldwater, TX, USA |

"After installing the motorized HANTEMP valve, which we control with a 4-20ma signal from our existing PLC, we established precise control of the -30°F suction. The Hantemp valve acts as another step of capacity control in our compressor sequencing and we were very impressed with the tonnage we are doing across the valve when compared with the standard BPR. I am sure we are going to look for opportunities to incorporate these valves in future designs."
-James Erwin, Vice President Refrigeration Design & Service Inc., Fairless Hills, PA, USA *Since the initial ball valve installation, Refrigeration Design & Service Inc. has purchased and installed an additional ball valve into a similar refrigeration application with a repeat of this success. |

"We contacted HANTEMP for an ammonia suction line application for an industrial ice machine. The valve that had been installed was creating too much pressure drop for this application. We installed a HANTEMP SSBW 2½" COBRA-NECK Ball Valve with an on/off actuator. The valve performs perfectly and has nearly no pressure drop. Plus, the stainless steel body provides a corrosion free, low maintenance control valve for our customer." -Delta Refrigeration, Pico Rivera, CA, USA |

"Our customer was having challenges with piston check valves in economizer side port applications. We needed a valve that would open and close in conjunction with the compressor operation, would not chatter at low load conditions, and would not allow any reverse flow when closed. We selected the HANTEMP COBRA-NECK® Ball Valve with an electric actuator for automatic control from the compressor control panel. The valve closes tight, and does not chatter at low load conditions. We also installed the ball valve as an isolation valve after the control valve to maintain low overall pressure drop." -Indianapolis, IN USA |

“We have installed the HANTEMP Controls stainless steel flange unions for several of our installations for connecting to other stainless steel components. The 316L stainless steel material is corrosion free, and is compatible with stainless steel equipment we are piping into, and there is ample space for welding without any bolt interference. Plus, we do not need to paint the flanges after installation.
We will definitely use the HANTEMP EZWLD stainless steel flanges on future projects that require stainless steel connections." -Pat Rainbolt, Construction & Engineering LoTemp Equipment Company, Omaha, NE, USA |

“We have been using the HANTEMP SSLL Stainless Steel Liquid Level Float Switches on our packages for nearly a year with promising results.
The SSLL Float Switch is reliable, and the stainless steel body doesn’t require any additional surface finishing (painting) after installation. We will continue to use the HANTEMP SSLL on our refrigeration packages." -H.A. Phillips Co., DeKalb, IL, USA |
