The Nortec Humidity Control System (Model No: 2573524) is an essential accessory for maintaining optimal humidity levels in various environments, especially in greenhouses and growth chambers. This system comes with three different size options for the Solenoid Valve (SV): NH100, NH200, and GH20.
The NH100 and NH200 Solenoid Valves are designed for larger-scale applications, where higher water flow rates are required. The NH100 Valve has a flow rate of approximately 3.5 liters per minute, while the NH200 Valve can handle a flow rate of around 7 liters per minute. Both valves are suitable for use with water or glycol solutions.
The GH20 Solenoid Valve, on the other hand, is a compact and versatile option for smaller-scale applications. It has a flow rate of approximately 1 liter per minute, making it ideal for use in smaller greenhouses or growth chambers. Like its larger counterparts, the GH20 Valve can also be used with water or glycol solutions.
The Spill-proof (SP) Fill Valve VLV is a crucial component of the Nortec Humidity Control System, responsible for maintaining a consistent water level in the humidifier reservoir. This valve ensures that the water level does not drop below the minimum required for proper operation, preventing the humidifier from running dry and potentially damaging the unit. The VLV is designed to be easy to install and requires minimal maintenance.
The Nortec Humidity Control System is an essential tool for maintaining the ideal humidity levels in various environments, ensuring the health and growth of plants, as well as the preservation of sensitive materials. The combination of the adjustable solenoid valves and the spill-proof fill valve offers reliable, consistent, and efficient humidity control. This system is an excellent investment for hobbyists, professionals, and businesses alike, ensuring optimal conditions for various applications.
