Tapwater station ModvFresh 4 Kascata - 400 kW - 160L/min - 4 units
Tapwater station ModvFresh 4 Kascata - 400 kW - 160L/min - 4 units - digitale regeling (professioneel/grote stations voor zeer groot verbruik.
Zeer geschikt voor lage temperatuur van bijvoorbeeld warmtepompen
Mogelijkheid tot tapwater circulatie systeem, mail of bel
Met digitale cv pomp regeling. Cv-pomp welke warm water uit buffer trekt kan van 10% tot 100% optoeren in vermogen. Hierdoor is het tapwater station geschikt voor hoge temperatuur buffertanken met temperatuur gelaagdheid. (prima voor cv haarden en biomassa ketels. De pomp zal het vat rustig ontladen en niet onnodig omwoelen qua warmte. (zeer geschikt voor hoge temperatuur buffers welke op het hoogste punt heet zijn en onderin zo koud mogelijk)
Ook zeer geschikt voor warmtepomp buffertank systemen op lage temperatuur. Dit tapwater station kan op lage temperatuur evengoed veel warmwater/vermogen halen.
Cv pomp is voorzien van pwm sturing.

Applications: with buffer tanks connected to standard heating systems, heat pumps, solar thermal and biomass systems. It provides DHW, avoiding phenomena of bacterial pollution, such as the legionnaire’s disease, due to stagnation of heated water. Control and management of the integrative heat source of the buffer tank to maintain the minimum storage temperature required. Optimal control of the return temperature to the tank thanks to the diverting valve control (optional valve).
The unit, by means of a dedicated electronic controller, modulates the speed of the primary high efficiency circulating pump, from a minimum speed of 10% up to 100%, in order to provide always a precise temperature of exploitation (e.g. 45°C). The variation of the requested flow is suddenly recorded by a digital sensor that gives the inputs of flow and temperature to the controller, which modulates the speed of the circulating pump accordingly.
Three models available, fully pre-assembled and pre-wired
• 50 kW, with flow rate from 1 up to 20 L/min, suitable for domestic use installations;
• 100 and 125 kW, with flow rate from 2 up to 40 L/min, suitable for small commercial installations.
Features
• High efficiency circulating pump and control of return temperature of primary loop by a diverting valve (optional);
• Function of thermostat integration of the buffer tank: it activates the energy source in case water temperature of the buffer tank does not comply with set up timetables;
• External sensor boxes to connect easily external sensors and relays.
• Delivered DHW temperature: 45°C with supply cold water temperature of 10°C. Consequently the power is about 98 kW at the flow rate of 40 L/min;
• The 125 kW model allows to operate with lower temperatures in the buffer tank, or to deliver the same flow rate at a higher temperature;
• Anyway the temperature of the DHW is adjustable every single degree up to 70°C;
• The minimum required temperature of the heat exchanger is 60°C in order to guarantee the declared performaces to the maximum flow (with 35 K thermal ∆t);
• A big surface plate weld-braised heat exchanger made of stainless steel AISI 316 guarantees a remarkable thermal exchange that allows a water return to the puffer with a temperature up to 15°C. This favours a perfect yield of the solar contribution or of the heat pump;
• Available with or without recirculation circulating pump (functionning “on request” or “by time bands”; adjustable temperature up to 40°C);
• Synchronous high efficiency recirculation circulating pump (in the models where it is present);
• The heat exchanger can be easily removed in case of maintenance and/of cleaning;
• A digital sensor allows an accurate power recording (total, yearly, monthly, weekly and daily);
• EPP insulation box (398 x 500 x 207 mm). A special back plate fixes the unit to the insulation box and it allows a quick fitting to the wall or to the buffer tank;
• The pump unit is supplied with 3/4” Male connections (pipe-union).
Technical features of ModvFresh 4
• Maximum allowed pressure (without water hammer): 10 bar
• Working temperature: 2 ÷ 95°C
• Headloss in the secondary circuit at the flow rate of 20 L/min (50 kW model): 4 mH2O
• Headloss in the secondary circuit at the flow rate of 30 L/min (100 kW model): 5 mH2O
• Headloss in the secondary circuit at the flow rate of 40 L/min (125 kW model): 6 mH2O
• Headloss in the recirculation circuit (at the flow of 5 L/min): 0,3 mH2O
Min. diameter size of the pipes: DN20 (Cu 22x1); DN15 for the recirculation line.
FIELD OF USE
For a maximum power of 125 kW and flow rate up to 40 L/min.
Nominal supply temperature of the buffer tank: 60°C.
Nominal inlet temperature from cold water supply: 10°C.
Nominal temperature of DHW: 45°C, adjustable from 30°C up to 70°C.
Recirculation line temperature adjustable from 10°C up to 40°C.
Sensor Box
For an easy and effective connection of the temperature sensors, valves or circulating pumps it is not necessary to act on the control unit, but it is sufficient to plug the cables in the automatic connectors of the sensor box.
