Similarities of ZETA145 Dehumidifier and GUARD70 Dehumidifier
As a company specializing in the production of commercial dehumidifiers, Preair has long invested significant manpower and resources into R&D, striving to produce dehumidification equipment that balances practicality and price advantage. To meet the needs of modern cultivation, we have successively developed 2 series of dehumidifiers: ZETA and GUARD. To facilitate customers' understanding and purchase, this article will focus on comparing and analyzing ZETA145 and GUARD70.
Firstly, the dehumidification capacities of the two machines are similar. Ignoring minor errors in the experiment, in a grow room with a temperature of 30℃ and a relative humidity of 80%, both the ZETA145 and GUARD70 dehumidifiers can achieve a dehumidification capacity of 145 liters of water per day.
Secondly, there are many similarities in the design and appearance. The ZETA145 ceiling dehumidifier features a shell made of sheet metal, with a front air inlet and a rear air outlet. There is a detachable grille on both sides of the machine near the inlet, facilitating the replacement of the filter screen. The control panel and drainage port are fixed on one side of the machine. The shell of the GUARD70 ceiling dehumidifier is also made of sheet metal, and the painting technology is mature, making it resistant to high temperatures and humidity and less prone to corrosion. It also adopts a design with a front air inlet and a rear air outlet, and the filter screen replacement grille is located on both sides near the air inlet. On the back of the machine, various third-party terminal interfaces are clearly arranged.
Overall, both machines boast a minimalist and elegant design, are user-friendly, and come with a long warranty, making them highly favored by commercial growers in Southeast Asia.
Main Differences between ZETA145 Dehumidifier and GUARD70 Dehumidifier
It is no exaggeration to say that GUARD70 boasts a fresher design, upgraded functionality, and better user-friendliness, making it an upgraded version of ZETA145. Here is a detailed description:
Different Colors
The ZETA145 ceiling dehumidifier has a black appearance, while the GUARD70 ceiling dehumidifier features a striking and comfortable combination of white and green.
Better Performance
The performance of the GUARD dehumidifier is comparable to that of the Quest dehumidifier. Its effective operating temperature range is from 13.3°C to 35°C, fully meeting the humidity control needs during the growth and flowering stages of cannabis. Even at a low temperature of 13.3°C, the device can continue to operate without entering defrost mode, ensuring stable dehumidification under low temperature conditions. However, the ZETA dehumidifier performs less well than the GUARD device at low temperatures.
Removable Control Panel
The control panel of ZETA145 is fixed at the back of the machine. The control panel of the GUARD70 is magnetic and can be attached to any position on the body for ease of use.
More Flexible Control Methods
The GUARD70 dehumidifier is equipped with an external humidity sensor interface, enabling more precise environmental monitoring and control. The system supports Modbus communication and APP control, allowing seamless integration with third-party environmental control platforms. Each port is labeled with a sticker for instructions.
Upgraded Refrigeration System
The refrigeration system features dynamic refrigerant pressure monitoring, which provides active compressor protection under various load conditions, thereby extending the service life of the compressor.
Smarter Auto-Defrost Function
An automatic defrost system with adjustable defrost timing and temperature setpoints allows flexible adaptation to complex low-temperature conditions, minimizing efficiency loss while ensuring safe operation.
More Durable Heat Exchange Components
The system utilizes thickened copper tubing, enhancing pressure resistance, heat transfer efficiency, and long-term operational durability.
Packaging Optimization
The packaging uses a cardboard box with wooden strips, making disassembly more convenient and efficient.
