HGA-M-01 Superheated Steam/Air/Gas Generator (1KW)
- Model: HGA-M-01
- Manufacturer: Micropyretics Heaters International
THE HGA-M-01 is a unique device that provides low to high-humidity air or gases like CO2, N2, Ar, and He mixture with H2O. The maximum power is 1KW for this unit. A high-temperature superheated mix of steam-air or steam-gas output. Note that the parameters for air and steam are given in the Unit Features tab. The unit has adjustable humidity.
The high-humidity steam/air mixtures will have varying temperatures depending on the mix. Please review the unit features in the adjacent tab.
Superheated steam is an odorless high-temperature gas (not to be confused with hot water mist). OPUMP-1 (water pump) is highly recommended for metering the water flow. Several more options are available and recommended. The airflow control option (flow meter) is generally required.
The BPAN-O-PLUS option is required only if power adjustment is contemplated. Please ensure minimum air and water flow to prevent burnout when using without using the BPAN-O-PLUS power controller.
Voltage: 110VAC (please note that a t 220-110V transformer is provided for countries where 110V is not standard). Please indicate the request on the pull-down menu in the selected options. The transformer can be used with the BPAN-O-PLUS models regardless of choice, i.e., BPAN-O-PLUS (110/115) or BPAN-O-PLUS (240). Please note that the transformer is rated for running the unit and the pump when used in a configuration socket – transformer-BPAN-O- PLUS (110/115) (optional only if power adjustment is required). Please have a qualified electrician install the unit.
Frequency: 50/60 HZ
Current: Approx. 9 Amps @ 110VAC
Power Consumption: ~1000 Watts
The size envelope is ~18″ x 2″ in Diameter without legs.
Safety precautions must be taken when dealing with hot gasses, including steam.
Safety: PLEASE DO NOT USE UNIT ON COMBUSTIBLE LIQUIDS. THE DANGER OF SUPERHEATED STEAM SHOULD BE WELL UNDERSTOOD. PLEASE WEAR GLOVES, GLASSES AND A HARD HAT. PROTECTIVE CLOTHING IS REQUIRED. STEAM CAN PENETRATE CLOTHES. Patents applied and pending.
Installation: Installation and use manual provided with the product. The airflow generator is in the user’s scope.
Options: The control thermocouple for the hot air generator part is included. Steam output temperature thermocouples and brackets are sold separately, or user may provide their own on their part. An electrical 110-120V 50/60Hz supply is required for this unit. 1 KW system requires compressed air input. Compressed air is user scope.

Typical Use: Where high temperature and high humidity steam is used, such as antimicrobial, soil, drying of ceramics, and sanitation. Use also for process simulation.
For NeverDown(TM) unit -replacements, please contact MHI at [email protected] at 513-772-0404 with the serial number.
Please click on the specifications tab for a typically expected performance at a known setting. Not all the setting widows for power mixture and temperature are known.
If the BPAN-O-PLUS power controller is not purchased, maximum power will require a minimum of 2.5 SCFM Airflow.
The temperature is controlled by water flow, airflow, and power controller (if purchased)
Potential uses: For drying, cleaning, layering, epoxy drying, and other film uses where superheated steam is required at one atmospheric pressure. Ideal for steam drying or steam oxidation. Product has uses in surface technologies, cleaning technologies, drying technologies, curing technologies, and nanotechnologies. Attempt use also for precipitating crystals of several small sizes, including nanocrystals from solutions. Precipitation droplet sizes may be controlled by controlling the rate of cooling, impingement conditions, and surface type.
High Humidity Control: Steam temperature and the relative mass of moisture in the steam-air mixture (specific humidity) depends on the water valve setting and air inflow setting. This unique device can give more than 40% specific humidity at temperatures greater than 100C (compare with a specific humidity of less than 3% in fully saturated air at room temperature, i.e., air with RH=100%).
Typical settings: This unit requires a compressed air source and a metered water pump like the O-Pump-1. Setting:
(Full power of 1 kW):
Air 1.45CFM (inlet at ~30C) and water 250ml in 45 mins (inlet 30C) yield a steam-air temperature of about 450C.
Air 1.45 CFM (inlet at ~30C) and water 330ml in 45 mins (inlet 30C) yield a steam-air temperature of about 350C.
Air 1.4CFM (inlet at ~30C) and water 200ml in 20 mins (inlet 30C) yield a steam-air temperature of about 250C.
Air 1.8CFM (inlet at ~30C) and water 200ml in 20 mins (inlet 30C) yield a steam-air temperature of about 150C.
The user must provide an airflow device from a compressor or gas bottle and regulate the flow with a flowmeter.
The unit come with a manual which has comprehensive valve setting data for the water (manual available only with purchase). These settings may vary with use and other conditions. The values above should be considered as approximate. Your results may vary with the unit and the type of use.
Options: Control Thermocouple for the hot air generator part is included. Steam output temperature Thermocouple and bracket is sold separately or user may provide their own on their part. Electrical 110-120V 50/60Hz supply required for this unit. 1KW system requires compressed air input.

Q: When do you dry with steam instead of drying with hot air?
A: There are many benefits to using steam but the main one is the availability of a gas with a lot of stored enthalpy at a lower temperature than corresponding dry air with the same enthalpy. So if you were interested in drying paper which has an ignition temperature of say 450°F, then the use of superheated steam at a much lower temperature may produce the same drying efficiency as hot air at a high-temperature which could be in excess of the paper ignition temperature.
Q: Is steam drying energy efficient? Is it better?
A: The answer is YES in many applications. Compared to boiling in hot water to remove dirt, superheated steam is faster and may not require the subsequent drying operation thus saving you time and money. There is also the possibility that because of the large enthalpy content and higher than 100C steam temperature, the cleaning could be more efficient, reach tough to clean spots, and eliminate more.
