PRO300 Dehumidifier VS PRO330 Dehumidifier

Differences between PRO300 and PRO330

Capacity:

Under the circumstance of 26.7℃ and 60% RH, the capacity of the PRO300 dehumidifier is 300 PPD, while the PRO330 dehumidifier's capacity is 330 PPD. When the temperature is 30℃, the RH is 80%, then the capacities of the PRO300 and PRO330 turn out to be 430 PPD and 500 PPD, respectively. When the temperature climbs to 32℃, the RH reaches 90%, the dehumidification capacity of the PRO300 can be 590 PPD, and the PRO330 can be 670 PPD. Choose PRO300 or PRO330 according to the requirements of the plant growth process.

Materials of the Refrigeration System：

The PRO300 dehumidifier adopts microchannel technology, which occupies less internal space. The PRO330 dehumidifier uses copper tube heat exchangers for higher energy efficiency and better performance. Energy-efficient units can help reduce operating costs over time.

Fans:

The PRO330 dehumidifier uses an EC fan with a double-speed selection. The PRO300 dehumidifier uses a single-speed AC fan.

AC (alternating current) fans use traditional induction motors, which are simple in design. These motors operate on the principle of electromagnetic induction. EC (electronically commutated) fans use brushless DC motors. These motors are more advanced and efficient. AC fans operate at a single speed and can't adjust their speed based on demand. EC fans are more energy-efficient because they can change their speed based on the cooling or ventilation needs. AC fans typically rely on external devices (like resistors or transformers) for speed control, which can be less precise. EC fans have built-in electronics that allow for precise speed control. EC fans generally have a softer start with a lower inrush current, reducing stress on the electrical system. They often have a longer lifespan due to the design of the brushless DC motor and the reduced wear and tear associated with variable-speed operation. EC fans may have a higher initial cost, but the potential energy savings over time can offset this.

Utilization area:

Greenhouses ranging from 5,000 to 20,000 square feet may require a dehumidifier in the range of 200 to 300 PPD. When you need to buy greenhouse dehumidifiers, you need to consider factors like plant density, ventilation, and regional climate.
