Description
Quantor QSI 221 – glycol chiller with cooling and heating
Quantor QSI 221 is the largest model in the QSI series, a mobile glycol chiller with an inverter-driven compressor, 21.7 kW cooling capacity and an integrated 5 kW heating element. It suits breweries and wineries with many or large tanks that want precise fermentation temperature control and sometimes also need to heat the product. The glycol chiller is an order item shipped directly to the customer, with price on request.
QSI stands for Quantor Smart Inverter. The inverter compressor, EC fans and electronic expansion valve regulate output steplessly between 15% and 100%, so the chiller only delivers the capacity that is needed. This means fewer compressor starts, longer service life and, according to Quantor, up to 30% lower energy consumption than unregulated systems. QSI 221 uses the refrigerant R32.
Benefits
- Stepless capacity control from 15% to 100% with an inverter compressor
- Up to 30% lower energy consumption than unregulated systems, according to Quantor
- Cools and heats in the same unit, with an integrated heating element
- Refrigerant R32, in line with the F-gas regulation
- Quiet hermetic rotary compressor and efficient MicroChannel condenser
- Insulated stainless steel tank, and all water-carrying parts are hygienic and corrosion-resistant
- Float switch for dry-run protection and a continuous bypass that protects the pump
- Easy operation via LED touch display
- Mobile on wheels, with fans on top and side panels that are easy to remove for maintenance
Applications
- Cooling and heating of must, wine, beer and other beverages such as cider, soft drinks and spirits
- Temperature control during fermentation
- Tartaric stabilisation and malolactic fermentation
- Cold storage of wine until bottling
- Maturation of young beer
- Cooling and stabilisation of spirits
- Room climate control (requires separate fan coil units)

Frequently asked questions about Quantor QSI 221
What does QSI mean?
QSI stands for Quantor Smart Inverter. The chiller has an inverter-driven compressor that adjusts output steplessly to demand.
Can QSI 221 both cool and heat?
Yes. The chiller has an integrated 5 kW heating element, so it can both cool and heat the product.
Why does QSI 221 use less power?
The inverter compressor adjusts output between 15% and 100% instead of switching on and off. According to Quantor, this gives up to 30% lower energy consumption than unregulated systems.
What power supply does it need?
QSI 221 connects to 400 V, 3-phase, 50 Hz and draws a maximum of 21.4 A.
