With many years of experience in CO2 commercial refrigeration, the Swedish manufacturer Green & Cool was the first choice for a Dutch engineering company to meet the increasing demand for CO2 refrigeration in the Netherlands.
The cooperation between Green & Cool and Assumburg Koeltechniek started already a few years ago and has already led to three transcritical installations at DekaMarkt supermarkets, that are part of a leading retail company in the Netherlands. Assumburg Koeltechniek has also installed Green & Cool's combined chiller and freezer unit Crystal at Dutch supermarket chain Vomar Voordeelmarkt. With a total of 200 installations of transcritical CO2 systems across Europe, Green & Cool could play at its strengths to meet the specific needs of the partner.
Smart software and cost-saving system
Besides a highly efficient complete refrigeration system, the engineers of Assumburg Koeltechniek were looking for a user-friendly control system that offers a comprehensive and reliable surveillance of the establishment. With GREENCO2NTROL, a software developed by Green & Cool, they found a unique and functional solution, offering also the possibility of remote control/steering, which avoids the need for a PC on site or any additional cooling or UPS system.
The refrigeration systems now installed at various DekaMarkt stores in the Netherlands is the Green & Cool Crystal, which in this case is equipped for extra hot gas desuperheat heat reclaim. The Crystal is a combined chiller and freezer unit, with up to six medium temperature (MT) compressors and three low temperature (LT) compressors. It is a popular model as only one unit can fulfil the complete MT/LT need, resulting in a lower total cost and an improved COP thanks to the LT side. With a maximum pressure of 60 bar, the system can stand a temperature rise longer than a 40 bar system in case of power outage, resulting in less damage and costs.
Technical specifications Crystal DX:

Design temp. (oC) LT-side: -37
Swept volume: 8,6 - 75,6 m3/h
Type of construction: combined chiller and freezer unit
System: direct expansion on the evaporator side and gas cooler side
Product range: available in up to 6 compressors in MT-side and 3 compressors in LT-side
