1) UL/CSA 60335-2-40 is on the horizon. UL Standard 1995 and CSA Standard C22.2 No. 236, two required standards that apply to heating and cooling equipment, are currently scheduled to sunset on Nov. 16, 2022, and Nov. 30, 2022, respec- tively. When these standards are withdrawn, the latest versions of the bi-national UL/CSA Standard 60335-2-40 will become effective, and UL/CSA 60335-2-40 will be mandated after Jan. 1, 2024. Part 2-40 refers to Particular Requirements for Electrical Heat Pumps, Air-Conditioners, and Dehumidifiers and is expected to broadly affect industrial climate control solutions across the automotive industry.

2) All standards point to reduced emissions. At the same time, the California Air Resources Board (CARB) has adopted legislation that prohibits the use of high-global warming potential (GWP) hydrofluorocarbon (HFC) refrigerants for USE and ULE equipment effective Jan. 1, 2023, and chillers effective Jan. 1, 2024. New U.S. Department of Energy standards will take effect within the same timeframe. The shared goal of these standards is to reduce greenhouse gas emissions, including HFC refrigerants.

3) The effort is global. UL/CSA 60335-2-40 is a binational standard that applies to the U.S. and Canada, but it’s based on the international IEC 60335-2-40 standard, which is currently being used to certify heating, ventilation, and cooling (HVAC) equipment using low-GWP refrigerants in Europe and globally.

4) Smart leak detection systems are a must-have — or just skip flammable refrigerants altogether. UL/CSA 60335-2-40 will require that chillers be outfitted with refrigerant leak detection systems, if they use flammable refrigerants. Rittal chillers don’t use flammable refrigerants in the first place, which leads to lower maintenance costs overall.

5) Blue e+ chillers are the only compliant option on the market today. Manufacturers are rushing to design systems that meet requirements of UL/CSA 60335-2-40. Meanwhile, Rittal’s Blue e+ climate control solutions are already compliant. As a company that prioritizes energy efficiency for its cost savings implications and for the planet, Rittal has a history of innovation in sustainable climate control. The Blue e+ line is the world’s most efficient range of chillers, providing energy savings up to 70% and using 55% less refrigerant due to microchannel technology. Benefits of the Blue e+ include:

  • Needs-based DC inverter technology with two regulating modes for high control accuracy
  • Touch-screen display for relevant performance data at a glance
  • Real-time remote monitoring, and if needed, quick modification of the unit’s settings from the operator’s smartphone or tablet via the Blue e+ app
  • Cooling capacities up to 20,000BTU (6kW) and suitable for use in environments ranging from -5°C to 50°C (23°F to 122°F)
  • Longer service from component-friendly cooling and integrated monitoring sensor technology

Rittal is prepared to help you navigate the transition from UL Standard 1995 to UL/ CSA Standard 60335-2-40.
