The First All-in-one Steady State Temperature and Humidity Logic Air Conditioner in The World

The Opticlimate RevomaxII boasts advanced Infinity DC inverter technology, providing the widest range of cooling capacities among all air conditioning units currently available. Unlike other products limited to 60%, it can operate as low as 20-30%, ensuring a consistently stable climate even with fewer fixtures installed.

The RevomaxII is the only real all-in solution for managing your interior climate, and has the unique property of being able to cool or heat, dehumidify, filter, and circulate air at the same time. You are no longer dependent on the outside temperature and can experience the perfect climate, all year round. You can even retain the ideal temperature during a heat wave. The RevomaxII creates an optimal distribution of air in the room, creating an even temperature. The temperatures can be exactly adjusted to your wishes and will be continuously maintained.

Super stable humidity. With the RevomaxII, the humidity will be within ±4%RH from the set-point (fig 1). With the PRO4, the humidity swing will be 20%, and normal air conditioners cannot even control the humidity.

Super stable room temperature. With the RevomaxII, the temperature will be within ±0.2°C from the set-point (Fig 2). dehumidification.

Super stable output (supply) temperature. With the RevomaxII, during dehumidification at night or day, the output temperature will fluctuate at most 0.4°C (fig 3). The temperature swing of the PRO4 can go as high as 40°C and as low as 10°C depending on the indoor temperature. For many applications and plant species this is very important. For example, with green vegetables like lettuce and herbs, high output temperature fluctuations result in stressed plants. The more stable the output temperature, the less the stress is for the plants. Because of this new feature, the unit can now be used for a much larger variety of applications and plants.

The above new features are made possible because of our patented double EEV (Electronic Expansion Valve) technology, and intelligent software. We are the only supplier with this technology. This will bring the RevomaxII to a new level of controllability, flexibility, and accuracy.

The RevomaxII units will also be optimized for growing with LED. When growing with LED, the room temperature rises more slowly than with HID lights, and photosynthesis will be less optimal. With the RevomaxII, the room will be heated up with the DC compressor in heating mode without using external electrical heaters. This way, the optimum temperature will be reached in the fastest possible way and optimum photosynthesis will be reached faster. During heating, the dehumidification process stays active to assure the humidity is still controlled.

Besides this, the RevomaxII units will come with a 7″ Smart Remote controller which can be connected to the internet by Wi-Fi or wired. With this you can control the RevomaxII remotely and receive alarms and warnings by e-mail.

The Safest System

The RevomaxII system has all kinds of built-in protection mechanisms that ensure it is one of the safest climate systems on the market.

Built-in Temperature Protection

The built-in temperature protection disconnects heat sources when a configured temperature protection value is exceeded. E.g. when the water supply is obstructed, your whole crop might be wasted.

Built-in Water Leak Safeguard

A built-in water leakage sensor ensures the water supply is cut off to prevent more damage. This may occur in the event of a burst pipe or broken link or connection, or a blocked sewer.

Fireproof System

The RevomaxII is fireproof. All of the electrical components, including the heating and connections, are contained inside the steel housing

SMS Alarm Outlet

The RevomaxII has an potential-free alarm contact for connecting devices like an SMS module.

The Smart Remote controller, when connected to Wi-Fi or wired, allows you to receive alarms and warnings by e-mail.

Improve Air Quality

Moisture is everywhere in the air and can have a negative effect on your health and your crops. High humidity can be very damaging and can cause mold, rot, rust, and a musty odor. Too much humidity can lead to dust mites and allergens. It is therefore essential for an optimal indoor climate control to manage humidity. The RevomaxII helps you to create the ideal environment under the most extreme circumstances.

The dehumidification function of all other (water-cooled) air conditioning systems on the market works together with cooling. During cooling, the air is automatically dehumidified because of condensation on the heat exchanger. If there is little heat in the air, the required temperature is quickly reached and the air conditioning stops cooling and thus stops dehumidifying. This results in a high humidity. Compared to competitors, the RevomaxII has the unique property of being able to continue dehumidifying after the desired temperature has been reached.

Prevent Harmful Substances and Unpleasant Odours

The built-in lightweight dust and carbon filter keeps the interior components free of dust and so-called volatile organic compounds (VOCs) and absorbs disturbing smells such as solvents, softeners, cooking and food odors, smoke and body odors. The dehumidification function also deals preventively with musty odors from mold formation due to condensation.
