HeaterLine. Long-term power.

The HeaterLine features extremely robust, units for professional use and a long working life. The housing and cylinder are made of corrosion-resistant stainless steel. The HeaterLine is available in 9 device sizes with steam output from 6 - 225 kg/h; steam output of over 45 kg/h can be achieved by putting several units together.

The units generate hygienic steam and are particularly safe to operate, efficient and environmentally friendly.

The units feature the VDE and GS test marks and conform to CE, CSA and EAC.

Product description

High safety.

1 to 5 high quality heaters in the stainless steel cylinder heat the water similarly to immersion heaters. In conjunction with the level control's float switch, the heaters' mechanical overheat protection provides double low liquid level protection.

Simple maintenance and long service cycles.

When operated with softened water or tap water, the minerals in the water (e.g. limescale) separate. SuperFlush the integrated flushing system, creates turbulence in the water during the partial blowdowns. In this way the limescale particles are stirred up and can be pumped out by the powerful blow-down pump. The quantity of hardeners which can collect in the coarse strainer is clearly reduced while the maintenance cycles are considerably extended.

The remaining hardeners collect in the durable removable coarse strainer and can be removed during maintenance. During the maintenance, plug connectors, a cylinder clamping ring and steam hose adapter enable a simple and quick approach. The removable unit cowling permits access from three sides. Even when using water, the entire flushing system is integrated into the unit, thus contributing to the optimal dimension of the HeaterLine.

If the heater type steam humidifier is operated with fully demineralised water, there are very few deposits and the maintenance requirement is minimal.

Modern microprocessor controls.

Thanks to its highly advanced microprocessor controls, the HygroMatik heater element steam humidifier HeaterLine offers quick control responses and maximum control accuracy. Optionally, it can be controlled using a remote control. If operated with fully demineralised water, the Comfort and ComfortPlus controls provide control accuracy of up to +/- 1%.

The units can be adapted to the water quality in question. The standby blowdown process prevents standing cylinder water in accordance with VDI 6022. The HeaterLine can be controlled proportionately in the range of 5 to 100% of the respective nominal output. The controls process all standard control signals.
