Chiller Retrofit & VFD Solutions

Chiller retrofit and VFD solutions. Extend the life of your equipment by years

Many ageing chillers can benefit from upgrades and modifications to improve operation and efficiency.

We offer a selection of upgrade services so that equipment can continue to provide years of dedicated cooling.

Furthermore, this is available on ALL brands HVAC equipment. This means that your equipment can continue to provide years of dedicated cooling.

One of the most successful energy management ‘tools’ ever applied to building HVAC systems is the variable frequency drive (VFD).

For more than 20 years, VFDs have successfully been installed on fan and pump motors in a range of variable load applications. This has resulted in energy savings varying from 10 to 35 percent (over conventional constant speed applications). Consequently, this equates to a return on investment between one to three years.

Arguably, the largest ‘pump’ in your HVAC system, is the chiller compressor(s) which has the largest draw of energy usage. Therefore, by applying a VFD to your compressor, it can result in effective energy and  cost savings. In other words, a great return on your investment.

Most conventional buildings are designed for their HVAC systems operating at full load, where in most cases, they only utilise the full load capacities for short periods of the year. Therefore the need for improved part load performance is in greater need now, than ever before. This means that by applying an energy saving modernisation kit, the McQuay / Daikin and third party manufacturer chillers can achieve just that.

Chiller evaluation

Book a comprehensive evaluation of your chiller, using non-destructive testing (NDT) techniques.

This includes:

  • Oil analysis
  • Eddy current test
  • Inspection of insulation
  • Tube inspection/cleaning
  • Inspection of electrical connections and controls
  • Inspection of all water flow sensors
  • Inspection of all calibrations of sensors

Part of the Modernisation Kit is to also upgrade the controls. This can be upgraded to the modern Siemens controllers. Upgrading the controls, will result in easier connection to ‘Daikin on Site (DoS),  Daikin Applied's  24/7 remote monitoring system.

Where HVAC equipment repair is not an option, we can optimise your buildings’ overall efficiency and energy performance through the following:

  • Equipment servicing and surveys
  • Plant and equipment replacement
  • Performance contracting and design underwriting
  • Installation and commissioning
  • Energy efficiency packages
  • Building energy rating surveys
  • Self-financing
  • Building management system (BMS) advice
SAVINGS CASE STUDY EXAMPLE McQuay MNG SE ST 145.2 air cooled chiller with a VFD applied based on Eurovent ESSER load profile. Unit operating for 12 hrs per day, 5 days per week, 52 weeks per year, the total estimated saving would be around £11,000.00 per year on a 510kW chiller.
