Construction: The incubators are available in eight sizes ranging from 27 to 980 liters. The inner casing is made of corrosion-resistant stainless steel, while the outer casing is constructed from sheet steel with a stoved epoxy paint finish. The design ensures no contact between the inner and outer casings, optimizing insulation to minimize heat dissipation. The walls and door are insulated with 70 mm thick glass fiber, providing excellent thermal stability. A silicone rubber gasket ensures a good seal, and an inner Plexiglas door allows sample viewing with minimal temperature loss.

Heating: The incubators use sheathed tubular heating elements made of stainless steel. In fan-circulated models, these elements are placed around the fans, while in convection models, they are positioned around the inner casing. A solid-state relay is used for switching the heating elements.

Internal Fan for Air Circulation: In fan-circulated models, the air flow ensures even temperature distribution. The fan and heaters are located at the rear, shielded by a stainless steel baffle. Air is drawn into the fan, passes over the temperature sensor and heating elements, and is then re-circulated.

Exhaust Air and Fresh Air Supply: Fresh air is pre-heated before entering the chamber through an access vent. An adjustable valve controls the exhaust air flow through a 30 mm diameter vent.

Temperature Control and Safety: Temperature is monitored by a Pt100 sensor and controlled by a microprocessor-based controller for high accuracy. An independent over-temperature thermostat provides class 3.1 protection. The PID digital controller displays set and actual temperatures and includes a heater indicator lamp. The control panel features an ON/OFF switch and a fault indicator lamp.

Equipment: The incubators come with multiple position shelving, with additional shelves available. A 20 mm diameter access port with a silicone cork is standard.

Performance: The incubators operate from room temperature +10°C to 80°C, with temperature fluctuation less than ±0.2°C and spatial variation less than ±0.5°C at 37°C. They are suitable for various laboratory and industrial applications, including microbiological processes and quality control.
