＜High-light intensity model＞ Dimmable

Plant Growth Chamber

This is equipped with high-light intensity LED lamps.
The temperature and humidity are controlled by a 3-position control system, contributing to energy savings. Optimal program control can be achieved based on the specific requirements of the cultured plants. All types are capable of continuous dimming.

Features

  • An operation touch panel with time display is mounted on the upper part of the main body, which allows easy operation.
  • Model L(P)H-□PFQ (S/D/P) T-S allows both constant operation at any temperature/light/ (humidity) and day/night switching operation.
  • Model L(P)H-□PFQ (S/D/P) -SP(C) allows a program control.
  • Model L(P)H-□PFQ (S/D/P) -SPC has a CO2 control function.
  • Five-sided illumination. The light can be continuously dimmed form 20% to 100% or 0%.
  • Model LHs don’t need a drain hose or a tank because of a forced evaporation system inside the chamber.
  • Three-position controller is used for temperature and humidity control (proportional control for heating), which provides low running costs.
  • The inner door has energy-saving functions, being used as one door or two up-and-down doors as per usual.
  • Two-level wind speed control is installed to protect wind-sensitive plants..
  • A hole of 40 mm diameter for measurement is included as standard.
  • Humidity control system can be selected from “only humidification” or “only dehumidification” or “both humidification and dehumidification.”

Options

  • Table for a water tank (Model LPH)　(Size:W300×D400×H900mm)
  • Evaporator for drained water (Model LPH)
  • Individual ceiling light control

* Temperature sensor: platinum resistance temperature sensor, humidity sensor: polymer film capacitive sensor, humidifier: ultrasonic humidifier, Carbon Dioxide Concentration Sensor: Non-Dispersive Infrared (NDIR) Spectroscopy Method.
* Power requirement does not include the power-outlet installed inside the chamber. The internal outlet can be used up to 1A.
* These chambers are designed to operate in ambient temperatures 15 to 30℃ in general. The specified performance may not be achieved depending on actual usage conditions.
* Supply purified water (disilled or reverse osmosis water) only. 
* When lighting, temperature setting should be 15℃ or higher.
* Keep 30cm or more clearance at both sides and the back of the product to prevent exhausted heat from being trapped and hindering the cooling function.
* The specified control accuracy for temperature and humidity applies when lights off.
* For long-term operation under conditions of high temperature and high humidity, please contact us for confirmation.
* Due to differences in wavelength characteristics, the illuminance and luminous flux of each colors differ.
* Illuminance and photon flux density values measured on the lower shelf are average values.
* Due to PWM dimming control, flicker may be visible at low output settings.
