The outstanding feature of this model is the presence of an Infra-Red dryer in it. Inside the unit there is an infrared heater, which offers a maximum temperature of 200°C from ambient. After each dip, the Infrared heater helps in drying the substrate. It provides uniform heating to the substrate. The temperature is swiftly attained so that the time taken for the dipping process is greatly reduced.The coating thickness can be easily controlled by adjusting the withdrawal rate and the viscosity of the coating solution.
Another advantage of this model is that it minimizes the energy consumption as the heater will be activated only after detecting the substrate and hence it can provide the substrate with accurate temperature.
Dip coating unit with infrared dryer has both manual as well as PC mode. In manual mode a user friendly front panel with keyboard and LCD display is provided to enter all dipping and withdrawal parameters where as in PC mode entire unit can be controlled by user friendly software. It is also possible to save programs for future use.
HOLMARC’s Dip Coating Unit with Infrared Dryer (HO-TH-02B) has been designed to keep operator involvement as minimum as possible so that variables like speed, duration, etc. are maintained accurately by microprocessor controller. Movements are achieved by a precision servo motor controlled linear stage that offers vibration and noise free operation Moreover this model dip coaters are specially designed for lower volume applications.
PID Controller is used for optimum heating of the substrate. Apart from other sensors that sense the temperature of the heating chamber as a whole, the infrared sensor gives feedback of the temperature attained by the substrate by monitoring its emissivity.
Our Dip coating unit can provide controlled immersion and withdrawal speeds for the substrates at user defined temperature (Max.200°C) which helps to have a uniform coating. The compact size and sophisticated design of the system make it ideal for research activities and in physics, chemistry and biotechnology labs.We hold expertise in designing and manufacturing custom models depending on the varying needs of the customer.

An infrared heater is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. Infrared heaters can be operated in vacuum or atmosphere. Infrared heaters are usually classified by the wavelength bands of infrared emission.
HOLMARC’s Dip coating unit with infrared dryer (HO-TH-02B), has a ceramic infrared heat system incorporated with it.
Key Features :
Compact and attractive design
User friendly keyboard & LCD monitor
User friendly software
Infrared dryer for precise substrate heating
Ceramic infrared heat system
Ceramic infrared heating elements are used in a diverse range of industrial processes where long wave infrared radiation is required. Their useful wavelength range is 2 - 10 µm.
Ceramic Infrared heating elements emit energy with peak emission wavelengths between 3.3 to 5.7 microns. By design a coil heating element of Nickel-Chromium alloy is embedded in a glazed ceramic body, which gives protection against thermal shock and prevents attack by atmospheric oxygen.
The refractory material has a high emissivity value in the range of 0.96 which approaches the ideal black body conditions required for efficient radiation.As these heaters have high resistance to moisture laden air and corrosive atmosphere, they are ideal for solvent removal, moisture evaporation and use in other adverse conditions.
