1. What is this unit designed for?

This is a floor-standing air-conditioning unit designed for greenhouse environments — specifically for growing vegetables, flowers, fruits and mushrooms. It provides cooling, ventilation, humidification and basic air purification to optimize growing conditions.

2. What is the model and who manufactures it?

The model is RZ30FR, manufactured by Ruidong Group (brand Ruidong or available as OEM). The product is made in Shandong, China.

3. What are the electrical requirements?

The unit operates on 380 V / 3-phase / 50 Hz. Ensure your site has a compatible three-phase supply and that electrical installation is performed by a qualified electrician.

4. What refrigerants does the unit use?

The unit supports R407C or R22 refrigerants. Note that R22 is restricted or phased out in many countries — check local regulations and discuss R407C as the preferred option for new installations.

5. What type of compressor and airflow does the unit have?

The RZ30FR uses a hermetic scroll type compressor for reliable refrigeration. Nominal airflow is 3,500 m³/h (cubic meters per hour).

6. How does the unit control humidity and ventilation?

The unit combines cooling, ventilation and humidification functions. Humidity control is achieved via the integrated humidification system and adjustable ventilation rates. Precise control modes and setpoint ranges depend on the controller option — confirm controller features when ordering.

7. Is installation supported?

Yes — Ruidong provides online guided installation support. However, on-site installation should be carried out by qualified HVAC/greenhouse technicians to ensure correct placement, electrical connection and refrigerant handling.

8. How is the unit mounted and what are the physical characteristics?

The unit is floor-standing (mounting: floor). It is offered in a large size suitable for single-span agricultural greenhouses with PC sheet covers and comes in grey color.

9. What greenhouse sizes or crop areas does this unit serve?

Effective coverage depends on greenhouse height, insulation, crop transpiration rates and climate. Airflow of 3,500 m³/h makes it suitable for medium to large single-span greenhouses, but exact sizing should be confirmed via a site assessment or by consulting Ruidong for a calculation based on your conditions.

10. What maintenance is required?

Regular maintenance includes cleaning/replacing air filters, checking humidifier components, inspecting condensate drains, and annual HVAC service for refrigerant, compressor and electrical systems. Follow the manufacturer’s maintenance schedule and keep records of servicing.

11. Are spare parts and service available?

Spare parts and after-sales service are available through Ruidong or authorized distributors. OEM configurations are supported as well — request parts lists and service plans from your supplier.

12. Is the unit energy efficient?

The unit is promoted as energy-saving versus older greenhouse systems, in part due to the scroll compressor and combined functions. Actual energy consumption depends on operating setpoints, duty cycle and local climate — ask the supplier for performance data and power draw for a precise estimate.

13. Does the unit include air purification or filtration?

Yes — the unit includes an air purifier/filtration function to help reduce particulates and improve air quality in the greenhouse. Filter types and efficiency levels should be confirmed at the time of purchase.

14. What about noise levels?

Noise levels depend on operating mode and installation. Scroll compressors are typically quieter than older compressor types, but for exact dB(A) figures request the acoustic specifications from Ruidong or your distributor.

15. What regulatory or environmental considerations should I know?

Check local refrigerant regulations — R22 may be restricted. Ensure refrigerant handling and disposal comply with local laws. Also confirm electrical safety standards and greenhouse ventilation codes. Your supplier can advise on compliant refrigerant options and installation best practices.
