LED Chambers

LED Chambers

Designed to set the standard for plant growth, the Percival LED Series features research chambers that allow specific control over the one research variable that has eluded precision – light!


These Chambers are specifically designed for plant growth light quality studies and other experiments requiring specific wavelengths of light.

There are many options for these chambers including additional humidity and ethernet connection. Customizable options including different size chambers are also available if these don’t suit your parameters.

  • Shelving White epoxy coated steel wire
    shelving. Each shelf is 27” D x 28 3/4” W (69.2 cm x 73.0
    cm). Shelves slide in and out easily on stainless steel rail
    assemblies (at lower elevation only). When shelves are not
    mounted on rail assemblies they are vertically adjustable in
    1/2” increments.The maximum growing height is 20 3/4”
    (52.7 cm) per tier.
    Finish Interior and exterior painted with highly reflective,
    environmentally friendly, high temperature baked white powder
    Refrigeration Self-contained air-cooled condensing
    unit with hot gas bypass system for continuous compressor
    operation, extended life and close temperature control. This
    continous running condensing unit ensures precise temperature
    control by alternately cycling refrigerant and hot gas to
    the coil; this also prolongs the life of the compressor, and
    eliminates the risk of ice build up in the coil. Solenoid
    valves have an extended stem for quiet and long life operation.
    Evaporator coil is ceiling mounted and incorporates
    twin air circulation fans in an aluminum housing. Heat rejection
    to ambient (standard chamber) =4500 BTU/hr.
    Temperature Safety Limit Controls
    (Experiment Protection) Adjustable high and low temperature
    controls, audible alarms and visual indicators are provided.
    The controls shutdown all the power to the chamber,
    and activates alarms. When the temperature returns to the
    normal range the system will automatically reset.
    Humidity Control (optional) Additive humidity control
    of higher than ambient to 65% (± 10%) lights on for set
    temperatures between 20° to 30° C. Humidity control of
    higher than ambient to 90% (± 10%) lights off for temperatures
    between 15° to 30° C. Extended humidity ranges available.
