DESIGN OF THE EXPANSON-H

Pressure maintenance system using pump(s) and an adjustable discharge device.
➤ EXPANSON-H, two-pump version
• Set with:
– two horizontal multi-stage pumps connected to tank by galvanized cast-iron pipe. A standby pump is available.
➤ EXPANSON-H, one-pump version
• Set with:
– one horizontal multi-stage pump connected directly to tank.
• Both versions have:
– an electronic regulation box (CE), with automatic change of pump starting order in two pump version;
– an adjustable discharge device with filter;
– a set of isolating valves and one check valve per pump;
– one set isolating valve (one-pump version);
– one control pressure switch and two safety pressure switches.
The assembly is mounted on a base and connected to a galvanized steel tank (200 to
1,500 litres).

Salmson: Electronically controlled Circulators

ELECTRONICALLY CONTROLLED CIRCULATORS Single and Twin-head Commercial heating 2 poles - 50 Hz Single-phase

CHARACTERISTICS

2 poles - 50 Hz
Single-phase

OPERATING LIMITS

Flow up to : 90 m³/h
Head up to : 11 m

APPLICATIONS

For accelerated water circulation for heating or cooling, with optimization of circulator
operating point.
• Central heating,
• Urban heating,
• Commercial or industrial installations,
• Cooling circuits.
New, old (renovated) installations or extensions.
Circulating pumps recommended for facilities
fitted with thermostatically controlled cocks.

ADVANTAGES

• ENERGY SAVING
- Optimization of the circulator operating point. Energy savings of up to 50% compared to a classic circulating pump.
• ALL-PURPOSE
- These circulating pumps can be adapted to all types of current piping.
• NOISE CONTROL
- They remove the whistle and noise in thermostatically controlled cocks,
- They adapt their speed automatically to the levels of comfort required.
• RELIABILITY
- Their entirely automatic operation does not require either upkeep or purge, - The circulating pumps shutdown by the ON/OFF control, start up for several moments once a day, so as to avoid any blocking due to periods of inactivity. - Electronically operated unit with a non volatile memory for data storage and for the protection of instructions in the event of electricity switch off.
- DXE (fitted with IF units optional):
built-in automatic changeover without exterior equipment.
