Anstan Technologies CC is a Proudly South African company that is committed to the manufacture of electrode and live steam humidifiers. Anstan also supplies imported Airsec dehumidifiers and AQUA ANSTAN electronic scale prevention unit.

The first electrode humidifiers produced by Anstan were supplied to Adcor and installed at the Pretoria Art Museum in 1989. They are still in operation today. Anstan company policy has always had an emphasis on research and improvement that has resulted in various improvements, innovations and new models. In 1990 Anstan invested in moulds for their large size steam generating tanks followed by moulds for their medium size tanks in 1991. Some four years later their small capacity models came onto the market.

For capacities above 40 kg/h units are manufactured with multiple steam generators. The present range of capacity duties for a single humidifier is from 1 kg/h to 150 kg/h. In the PSA series, multiple generator models have a high capacity pump as well as a normally open drain valve.

Fan units are available for normally stand alone applications. Present models have stainless steel steam separators for capacities above 5 kg/h. High quality steam is discharged from the fan units resulting in a high standard of absorption.

All Anstan electrode humidifiers have steam-generating tanks that can be opened and cleaned. The tanks have slip on stainless steel clips and soft silicon O-rings to afford quick servicing.

Since January 2000 all Anstan humidifiers have drain valves with robust 24 VDC coils. These have 22mm orifices on the PSA series, ensuring a high flow rate and good dirt handling capability. This is another unique Anstan feature. Control is exceptionally good.

Anstan humidifiers are noted for the low maintenance and long service life. (See the report on our humidifiers at Air Force Headquarters). An important feature is the “Drain Watchman” which transmits a warning signal if the discharge flow becomes restricted. This signal can be used in various ways including cessation of the steam output or as an input to a panel or BMS or other options.

Anstan is a proudly South African manufactured humidifier with more that 20 years of experience in South Africa and neighbouring countries and In 2003 Anstan humidifiers were credited with the Proudly South African mark.
