Standard Features:
4 model sizes 32, 39, 53 and 108 litres
temperature range from + 5° C up to + 60° C
forced ventilation by Peltier fan
casing and working chamber of stainless steel material 1.4301
double doors – inner glass door, outside stainless steel door
adjustable microprocessor overheat controller ( TWW) protection class 3.1 according to DIN 12 880 and additional mechanical temperature limiter
serial interface RS 232 incl. MEMMERT-software „ Celsius 2000“
parallel printer interface for EPSON ESC/ P2-compatible printers
chip-card control incl. 1 MEMory CARD XL
works calibration certificate for 37° C
Control and Heating Concept:
Peltier-heating-/ cooling system ( heat pump principle) integrated in the rear
adaptive, fuzzy-supported PID-microprocessor controller
temperature setting and LED temperature display with 0, 1° C resolution
multifunctional programming through 5-digit LED digital display
Advantages compared to compressor-type cooled incubators:
reduction of energy consumption of up to 90% ( ! )
remarkable temperature distribution being better than + / - 0, 3° C ( from 10 – 37° C) and variation of temperature with time of approx. + / - 0, 05° C
no refrigerant thus no special arrangements for disposal
minimal emission of noise
inevitable condensation due to physical reasons does not take place in the working chamber ( water droplets) but outside in the cooling unit of the Peltier module
High-performance compressor-type cooled incubators are recommended
for temperatures below 5° C
short cooling-down times
for breeding bigger quantities requiring larger working chambers – so far Peltier-technology is not yet economical for this application
