Solo 1

Pump unit to load one buffer tank
Compact fully assembled pump unit to supply the heat produced by a solar thermal installation with High Flow or Low Flow operating mode. Suitable to be used with 1 buffer storage tank.
It is supplied fully insulated and pre-wired, with pre-programmed controller and it allows a fast and easy mounting.
The unit consists of:

Primary solar circuit:
  • Flowmeter with flow regulation with filling and draining valves. Alternatively a digital flowmeter is also available.
  • High efficiency synchronous solar circulating pump.
  • 3-way return ball valve with check valve 10 mbar supplied with in-handle thermometer.
  • Security unit 6 bar with manometer ø50 mm 0-10 bar with 3/4” male connection to the expansion vessel. End of drain side: 3/4” F.
  • Supply ball valve with check valve 10 mbar supplied with in-handle thermometer.
  • Air vent made of brass with automatic vent valve and isolating valve.
Heat exchanger:
  • Weld-braised plates heat exchanger made of stainless steel AISI 316 suitable for several powers.
Secondary circuit:
  • TÜV security valve 3 bar, 50 kW. End of drain side: 3/4” F
  • High efficiency synchronous circulating pump.
EPP insulation box (Measurements: 576x585x190 mm).
A special back plate fixes the unit to the insulation box and it allows a quick fitting to the wall.


PN 10. Constant temperature on the solar circuit 120°C;
(short time: 160°C for 20 s).
Maximum temperature on the secondary circuit 110°C.
Available external connections:

  • 1” Male for solar circuit.
  • 3/4” Male pipe union for the secondary circuit.
FIELD OF UTILIZATION:
For power up to 35 kW. One buffer storage tank.
Kvs value: see the diagram here below.

A special ball valves kit, available upon request (to be ordered) completes the unit.

ModvSol Solo 1

Heat supply pump unit to load one buffer tank. Suitable for a solar collectors surface up to 70 m2.

The pump unit, as shown in the illustrative scheme at side, gets the heat from the primary circuit (solar) and brings it to the heat exchanger. Then the thermic energy is tranferred to the secondary circuit, and in the specific case of ModvSol Solo 1, the loading of the buffer tank is done in only one point, because the pump unit cannot manage the control of the stratification.
To do the loading in stratification, use the pump unit ModvSol Solo 2.


NOTE: The schemes are incomplete and to be considered just as an indication.

It is possible to select two versions for each model indicated in the above table: one with mechanical flowmeter, another with digital VFS sensor.

Models with mechanical flowmeter:
the flowmeter has a measuring range of 8-28 or 8-38 l/m, default value according to the specific model selected. Product codes of these models have respectively the options 28 or 38. For instance: Solo 1, High Flow, with an exchanged power of 23 kW: code 031200-40-38-LT.

Models with digital VFS sensor:
all these models have the VFS sensor with a measuring range of 2-40 l/min. Product code of these models have the option 40. For instance: Solo 1, High Flow, with an exchanged power of 23 kW: code 031200-40-40-LT.
