LH50 PLUS
process system - for heating and cooling of external applications
Presto PLUS - Highly Dynamic Temperature System
Instruments of the PRESTO series are the ideal solution for highly precise,
external temperature applications. They offer rapid heating and cooling, wide
working temperature ranges without changing fluids as well as highest
performance with a small footprint. The self-optimizing controller (ICC Intelligent Cascade Control) provides excellent temperature stability and
optimized control. The classic PID control parameters are available at the
touch of a button for modification at any time. All models have an interactive
4-line LCD display as well as a bright VFD-Info-Display. All this together with
the splash-proof keypad and the high temperature cut-out (safety value)
ensure safe and convenient operation. Reciprocal sensor monitoring,
self-test after switch-on, pump motor and compressor overload protection as
well as permanent performance supervision of sensors guarantee reliable
perfo rmance and provide high safety for your samples. Analog connections,
digital interfaces and the optional Profibus allow future-oriented automation
technology. The high standard of heating, cooling and pump capacities in
combination with outstanding ICC temperature control help to produce
reliable and quick results.
