EuroShop 2020 – Products & Innovations

21. April 2020

EuroShop 2020 was a stunning success! Packed with interesting conversations and a good atmosphere, the five days in Düsseldorf went by in a flash. Again, a huge THANK YOU to all of our customers, partners and the many interested parties who came to our stand and learned about our new products.


Our key trade fair highlight was the new ROXSTAmicro CO2 condensing unit. The small series is ideal for plug-in applications, conversions and smaller markets. We presented the novelty for the first time at the EuroShop in air and water-cooled versions. The unit has already been used in initial projects. To be able to offer the product in a series in the future, we are currently carrying out various long-term tests in our in-house test centre – with the aim of being able to bring ROXSTAmicro to the market in the third quarter of 2020.

  • For medium & low temperature cooling – plug & play
  • Air-cooled version with gas cooler & heater combination for food retail / commercial kitchens / cold rooms
  • Water-cooled version with plate heat exchanger for combination with water chillers / dry coolers
  • Speed-controlled, two-stage rotary compressors
  • Solution for retrofitting / expansion
  • Compact design
  • Ambient temperature: 0…43 °C


Our new CO2 series solution ROXSTA G6 was developed for larger supermarkets and hypermarkets. ROXSTA G6 can also meet many requirements in food production and logistics. The combination of powerful 6-cylinder compressors with frequency-controlled 4 or 6-cylinder guide compressors enables an extremely compact design for this system size but does not ignore the optimally coordinated partial load requirements. ROXSTA G6 has already proven itself in a few projects and has now been fully introduced by us.

  • Medium & low temperature cooling up to 550 kW
  • 6-cylinder compressors
  • 130 bar high pressure
  • Heat recovery
  • Increase in efficiency: parallel compression / EVALIFT / TEKOJET
  • Hypermarkets / food production / warehouses


The new RANSTAheat propane heat pump combines building heating and air-conditioning in a compact system for outdoor installation. Depending on the building area, three sound insulation variants are available. The equipment enables smooth operation from an ambient temperature of -20 to 40 °C.

  • Heating up to 189 kW / air-conditioning up to 164 kW 
  • Reversible heat pump
  • Heating & air-conditioning in one system
  • Variable speed control
  • Energy efficiency class A+
  • Efficient defrost

ROXSTAcube mini

The transcritical CO2 unit ROXSTAcube mini has already proven itself in various projects. The very compact unit with all the necessary functions is tailored to the requirements of discounters, organic markets or smaller supermarkets. The newly designed housing can also be easily retrofitted during operation.

  • Medium or medium & low temperature cooling
  • Small capacities up to 50 kW
  • Standardized, compact, easy to handle
  • Compact design
  • Indoor & outdoor installation
  • Two housing variants – Noise reduction 10/15 dB(A)
  • Optional heat recovery for hot and process water


The transcritical CO2 unit ROXSTAsmart has been reduced to the essential components for easy operation. Operators receive an operationally reliable, intelligent unit that – thanks to efficient cooling – generates the right temperature at all times for the goods. Refrigeration companies receive a refrigeration solution for easy and understandable handling of CO2. Handling, installation, control and maintenance are manageable and easy to implement.

  • Medium & low temperature cooling up to 150 kW
  • Indoor & outdoor installation
  • Two receiver sizes: 165 / 2x 165 L
  • Heat recovery with mounted water pump
  • Gas cooler bypass
  • Suction gas heat exchanger (MT / LT)
