Series
Series of digital thermoregulator for regulating the temperature that execute
1B type actions (EN 60730-1).
of digital temperature regulators that satisfy the simplest requirements in
the field of refrigeration. They may be used as regulators for the handling of:
- Static refrigeration units (with no fan on the evaporator) operating at normal
temperatures (over C)
