This custom thermal and humidity-controlled enclosure is built to house an engineering projector in outdoor or unconditioned installation environments. Each enclosure is configured around the projector model, projection direction and site conditions supplied by the buyer. The enclosure is optional equipment and the projector is not included. Dimensions, weight and airflow are determined for the selected projector and confirmed after drawing approval rather than supplied as one fixed universal size.
The enclosure controls its internal temperature between 5 °C and 40 °C. Setpoint accuracy is listed at 0.1 °C. A 1,200 W heating system starts when the outside ambient temperature falls below 5 °C. Cooling starts when the internal enclosure temperature rises above 30 °C, and the switching thresholds can be configured for the installation. While the projector is running, the cabinet heating function is automatically released.
These values describe different parts of the control logic: the 5-to-40-degree range is the internal control target, −5 °C to 40 °C is the specified outside environment, and 5 °C is the heating trigger.
Internal humidity is controlled between 10% and 80% RH with 1% setpoint accuracy. Dehumidification starts above 75% RH. An internal heated-air device helps keep the projection window free of frost and fog, supporting a clearer optical path when external temperature and humidity change. The enclosure is specified for outside humidity from 0% to 100%, while the internal control system manages the operating space around the projector.
The enclosure combines temperature control, humidity control, dust protection, water protection and insect protection for continuous outdoor duty. Climate control is specified for 7 * 24 operation throughout the year. The source specification describes protection up to IP54–IP65, confirmed per project; the final grade depends on the actual structure and site conditions. The enclosure should therefore be selected and quoted against the installation rather than treated as one universal off-the-shelf cabinet.
The enclosure structure consists of an outer body, a supporting frame, a projector mounting platform and the functional climate-control structure. The casing can use 1.5 mm cold-rolled steel or 201 stainless steel, with a galvanized inner shell. Galvanized sheet, aluminium-plastic material or other special materials can also be considered according to the project. The exterior receives anti-corrosion, anti-rust and anti-static baked paint. Available colours include matte black, off-white, dark grey and army green.
The projection opening uses optical ultra-clear glass with 95% transmittance. Coated optical glass is available as an option. Replaceable dust filters are used at the air inlet and outlet, and the outlet includes a high-strength grille window. The feet and door structure are reinforced for wind resistance after installation.
A removable internal mounting platform makes projector placement and service access easier. Linear tilt adjustment is available up to 10 degrees, with a larger adjustment angle available as a custom option. The multi-door enclosure structure gives technicians access to the projector, filter and internal components without dismantling the full cabinet. The replaceable filter has a listed service cycle of 6 to 9 months; actual replacement timing depends on dust, insects, operating hours and local conditions.
The listed standard power requirement is 220 V, 50 Hz, single phase. The internal multi-function socket is available in 16 A or 10 A form. Export voltage and frequency versions must be confirmed for each order rather than assumed. The control system uses external, high-temperature and high-humidity signals with programmed internal and external air circulation.
The standard configuration can include a custom outdoor cabinet air conditioner, circuit breaker, high-volume fresh-air fan system, low-voltage long-service fan, DC switching power supply, high-precision temperature and humidity sensor, self-stabilising heating elements, internal-circulation dehumidification module, LCD display module and microcontroller temperature-control module. Final component selection follows the approved project configuration.
Optional functions are confirmed separately and are not part of every standard enclosure. Available project options include:
The final option list is recorded in the approved drawing and commercial scope.
Send us the projector model, projector dimensions, heat-output information, projection direction, mounting method, site temperature and humidity, local voltage and frequency, required protection level and any remote-monitoring needs. We will use this information to size the enclosure, position the mounting platform and projection window, prepare the drawing and confirm the quotation. Enclosure dimensions, weight, airflow and total power are project-specific and are confirmed after drawing approval.
