HEATING, VENTILATION & AIR CONDITIONING
The HVAC sector covers a large variety of collective structures such as residential and office buildings, commercial and service facilities and also district heating and cooling networks where fluid management is crucial. We rely on many years of experiece and we offer a wide range of products for heat transfer systems and ventilation systems in order to control the indoor air quality and regulate temperature and humidity.
Radiator equipment and heating floor components
Our range of heating floor components includes stainless steel and brass distribution manifolds, fittings and accessories for distribution manifolds, accessories for heating floor slabs, and peripheral insulations.
In our radiator equipment range, we offer thermostatic valves to regulate the water temperature in radiators. They can be switched from manual to thermostatic mode by replacing the handle with a thermostatic head to maintain the desired temperature automatically.
You can find radiator air vents and drain cocks. They are essential for manually or automatically removing air from the radiator during initial filling or regular operation. They are horizontally or vertically installed on top of the emitter or generator: steel radiator, flooded exchanger, or unit heater...
We also offer hydraulic towel heaters with their electric sets. The towel dryer, for central heating, ensures a healthy atmosphere in your bathroom and gives you the pleasure of using dry and warm towels. Depending on the model, the towel dryer can be equipped with an electrical system to use while the central heating is off. We supply white, chrome and black towel heaters.
Our range of heating floor components includes stainless steel and brass distribution manifolds, fittings and accessories for distribution manifolds, accessories for heating floor slabs, and peripheral insulations.
Building control
We offer a building control range, including mixing valves, diverting valves and hydraulic units.
Our mixing valves are threaded or flanged 3 or 4 ways. We also offer electric actuation and regulation devices.
3 and 4-way mixing valves are mainly used in heating systems to mix hot water from the generator (boiler, solar collector, heat pump...) and cooled return water. This mixing allows an optimal controlled temperature to be achieved.
Our diverting valves are used to bypass the fluid in heating systems automatically.
We also supply direct or mixing hydraulic unit modules for radiator circuits or underfloor heating systems, allowing a simple and efficient connection between the energy source and the heating circuits. The units consist of a 3-way mixing valve (potentially actuated), a circulating pump, a regulation device, built-in ball valves with thermometers and an antithermo-siphon check valve, and insulation.
Circulators
We supply a range of circulators for domestic and collective use with their accessories. They are energy-efficient electronic pumps for water circulation in all residential heating and cooling systems.
We also offer sanitary hot water circulators for standard and very low consumption.
Our range of circulators allows the replacement of older three-speed circulators due to their size and functionality. Installation is easy thanks to the unique sequential adjustment button and access to the motor shaft for maintenance.
Expansion tanks
We supply a range of closed and open expansion tanks with accessories.
The closed expansion tank absorbs water volume variations due to temperature changes in heating and cooling systems. On the other hand, the open expansion tanks absorb water volume variations due to temperature changes in solid fuel heating systems. How do differential valves work? They are used in variable flow systems, managed by control valves (thermostatic valves, thermoelectric controls, zone valves). Modulation and closing of some networks result in a decrease in the required flow rate and a significant increase in the flow rate of those that remained open.
The differential pressure valve limits the pressure difference by diverting part of the flow to the return, thus avoiding wear and noise. The setting of the valve corresponds to the pressure drop of the most unfavourable circuit. To divert large flows, several valves can be installed in parallel. We also supply differential valves.
Air vents, separators and safety valves
The automatic air vent allows the heating system to operate in the best conditions. It eliminates air, the presence of which disturbs heat exchange, causes noise and promotes corrosion of the circuits.
Our automatic air vents are available in various types: compact, standard, solar, and heavy duty.
In heating installations, the dirt separators for domestic and collective use allow for collecting impurities and sludge in suspension, thus ensuring good functioning and greater installation longevity.
We supply a range of safety valves made of brass or bronze. The safety valve is used for heating installations in buildings and industry. In the event of excess pressure caused by a failure of the control and limiting device of the structure, the valve allows the heat produced by the boiler to be discharged. We offer safety valves for high temperatures, such as solar heating.
Self-regulating heating cable
Our range of self-regulating heating cables is designed for anti-frost protection, temperature control, roof snow removal and ramp protection. It also includes thermostats with a 3m contact probe and a ready-to-use cable set.
Instrumentation
Our instrumentation range includes thermostats, aquastats, flow switches, pressure switches, pressure gauges and accessories.
Thermostats are used to control room temperature. We provide standard mechanical or digital thermostats. Some thermostats offer programming functions.
- Programmable thermostats allow to program 3 ranges per day and to manage weekly programs.
- Connected thermostats are directly connectable to the internet, remotely controlled by a smartphone or a tablet, thanks to a mobile application. They are compatible with most electric and hydraulic systems.
Aquastat is a device to control the water temperature in the heainting system. It exists security aquastats with manual reset and control aquastats. Our aquastats are available with spring, plunger or remote sensors. The flow switch or paddle wheel flow sensor is used to detect the presence or absence of hydraulic flow in a heating system. Pressure switch with change-over contact can be used in monitoring and alarm control applications. We offer infrared or temperature probe thermometers. We also supply various kinds of bi-metal thermometers: with spring tie, copper tie or plunger, and quick reactivity. We provide thermometers specially designed for gas and smoke, boiler and industrial use. They measure temperature and are mounted on pipes or tanks. The plunger must be fully immersed in the fluid to be monitored.
Solid fuel boiler equipment
Our solid fuel boiler equipment range includes thermic valves, draught stabilisers and regulators.
In solid fuel heating systems, the thermal valve allows full or partial recirculation of the boiler water in order to quickly reach the intended boiler temperature.
The draught moderator increases the efficiency of your heating equipment, reduces fuel consumption and maintains ideal operation despite external disturbances. It also serves as a safety valve in case of overpressure.
The draught regulator installed on a solid fuel boiler automatically regulates the air flow rate at the inlet, thanks to its immersed thermostatic probe.
Solar heating equipment
Our range of solar heating equipment includes transfer units. Transfer units are used in the primary circuit of solar systems to manage energy recovery and ensure the proper functioning of the primary circuit.
You will also find controllers, circulators, expansion tanks and accessories, specially designed for solar heating systems.
We offer standard, with two exchangers or wall mounting sanitary hot water tanks with capacities from 150 to 1500 l, for the production and storage of domestic hot water. Our range also includes storage and exchanger tanks for heating water storage and sanitary hot water production. The storage tank is used in installations where one wishes to store the energy produced by a discontinuous source (solar, wood boiler, etc.) and use it in a heating installation (radiators or floor).
Renewable energy tanks
This range of renewable energy tanks or buffer tanks includes standard and premium mixing water tanks for heat pumps. This range covers ErP class A, B and C.
In heating systems, the mixing tank allows: for increasing the volume of water in the system, working with different water temperatures, decanting sludge and purging air.
In air-conditioning systems, the mixing tanks makes it possible to: increase the volume of water in the system, thus limiting the number of chiller starts.
The range also includes heating or cold-water tanks. The storage tank is used in installations to store the energy produced and used in heating (radiators and/or floor) or/and cooling installations.
