Rapid and energy-saving temperature changes in the environmental chamber
Perfect environmental simulation for climate test and temperature test
The climatic test chamber CTC and temperature test chamber TTC are, with a rated power of 7000 Watts, extremely powerful due to the optimally coordinated heating and cooling technology. Largest possible energy efficiency and reduction in noise had been two criteria for the Memmert engineers to fulfill. With a chamber volume of 256 litres, they provide plenty of space to offer, yet have a low floor space requirement because of their narrow and compact construction. In addition, the appliances can be conveniently moved on castors through any standard laboratory door.
Refrigerant R449A significantly more climate-friendly than R404A
The refrigerant R404A is only permitted without restriction until 31 December 2019 due to its high Global Warming Potential. In order to ensure that both the climate test chamber CTC as well as the temperature test chamber TTC can also be operated beyond this date, Memmert has reacted early by switching to the refrigerant R449A from April 2018 on. Existing appliances can also be converted to the new refrigerant in the “drop-in” or “retrofit” process, depending on the application.

Temperature-humidity working range CTC
Not all climate chambers are the same. The humidity content of the chamber load, the ambient conditions and the respective temperature-humidity working range are decisive factors in the selection of the right appliance. In the adjacent diagram, you can see the possible temperature/humidity combinations for our climatic test chamber CTC.
Within the respective temperature-humidity range, condensation-free permanent operation is possible. To which extent condensation may occur in the threshold range depends on the humidity content of the chamber load and the ambient conditions.
