Temperature and Humidity Cabinets with Shelf Lighting TRHSL

  • Product Testing and Quality Control
  • Research and Development
  • Insect Research (Drosophila)

Our Australian Made temperature and humidity cabinets control and maintain specific temperature and humidity levels within the cabinet. The TRH range also extends to these models with high intensity LED shelf lighting. The lighting provides additional environmental control and can be used to regulate the photoperiod, the length of the light period in the diurnal cycle of 24 hours, which is important for certain types of experiments or growth processes.

Overall, the combination of temperature, humidity, and lighting control in a single cabinet provides a convenient and efficient way to maintain specific environmental conditions for a wide range of applications.

Overview

The TRHSL has its lighting fitted to the underside of the internal shelving, providing light directly above your shelves for unobstructed, direct light. 

The TRHSL Humiditherm Shelf Lighting Cabinets are designed with innovative features to ensure optimal conditions for a wide range of research applications. Here are some of the key benefits and applications of our cabinets:

Key Features

  • Shelf Lighting: Shelf lighting inside a temperature and humidity cabinet ensures that all samples receive consistent and uniform light exposure. This is crucial for experiments that require controlled lighting conditions, such as plant growth studies and tissue culture. Uniform lighting helps in achieving more reliable and reproducible results by eliminating shadows and uneven light distribution that could affect the outcomes of the research.
  • Precise Control: These cabinets maintain conditions that are critical for research where temperature, humidity, and lighting need to be precisely controlled, including:
    • Drosophila research
    • Entomology
    • Seedling germination
    • Plant pathology
    • Plant production
    • Tissue culture
    • Propagation
  • Multiple Sizes: Available in three sizes:
    • Single-door 300L capacity
    • Single-door 460L capacity
    • Double-door 850L capacity
  • Uniform Airflow: An upward, fan-forced airflow maintains superior temperature uniformity within the cabinet.
  • Monitoring and Customisation: A 50mm cable/monitoring porthole is located in the side wall for remote measurement devices. Carbon dioxide control is optional in all sizes, allowing customisation to suit your application and budget.
  • Durable Construction: With a Colorbond exterior, 316 stainless steel interior, and 304 stainless steel shelves, these cabinets are highly corrosion-resistant and easy to clean.
  • Mobility: All cabinets are fitted with heavy-duty lockable castors for easy movement and servicing.
  • Options: Additional stainless steel shelving, water feed tank, glass or solid door, models with shelf or door lighting, CO2 control.

STAR X Touchpad Control System

The STAR X touchpad control system allows for easy adjustment and programming of temperature and humidity settings:

  • Real-Time Synchronisation: Synchronise programmed settings in real-time.
  • Ethernet Connectivity: Connect to a PC for remote operation of all functions.
  • Data Logging: Logs up to 365 days of performance data to onboard memory, with a live trend screen for quick performance checks. Logged data can be downloaded to a USB flash drive for archiving or review with any simple spreadsheet program (Microsoft Excel or similar).

Lighting Options

Based on nearly 100 years of experience with lighting technologies, Vossloh-Schwabe develops and manufactures LED solutions that can be tailored to suit specific applications. The TRHSL uses high-output LED lighting in three colour options:

  • 4000K (Neutral White): Closest equivalent to Cool White T5 fluorescent lamps, providing a neutral spectrum.
  • Leaf (2700K): Optimised for vegetative growth of plants and vegetables, with increased spectral emission in the far red and green spectral ranges.
  • Bloom (1900K): Optimised for ornamental plants and young seedlings, supporting flowering and initial growth stages with a focus on blue and red spectral ranges.

Benefits

  1. Enhanced Research Accuracy: Precise control of environmental conditions ensures reliable and reproducible research results.
  2. Energy Efficiency: External lighting and high-output LEDs reduce heat generation and energy consumption.
  3. User-Friendly Operation: The STAR X 10" touchscreen control system simplifies the adjustment and monitoring of cabinet conditions, making it easy to maintain optimal research environments.

Support & FAQs

At Thermoline, we strive to supply helpful customer support to ensure that you get the most out of our products. We are committed to providing whatever support our customers need, wherever they are in the world. If you can't find your solution in the below FAQs or Knowledge Base, please contact our friendly support team.

How do you maintain humidity in a chamber?
A refrigeration system is ideal for doing this. The evaporator coil in the chamber attracts moisture in the air, causing it to condense into water, which can then be drained away. A refrigeration system will help control temperature and humidity. Also, note that humidity is always relative to temperature; therefore, to be able to control humidity accurately and precisely, you need to control the temperature as well.
What is a temperature and humidity cabinet?

The purpose of the TRH temperature and humidity cabinet is to simulate and test the effects of various environmental conditions on products, materials, or samples in a controlled and repeatable manner.

These chambers are typically used in research and development, quality control, and manufacturing processes across a variety of industries such as electronics, automotive, aerospace, and pharmaceuticals.

Can I store a series of TRH cabinets adjacent to one another?
Yes, absolutely. You'll need to have enough space between cabinets to ensure that the exhaust from one does not blow into the next cabinet causing a reduction in performance. If space is an issue, please contact us about our innovative deflectors that allow chambers to be installed in close proximity to one another
Why would I need a temp and humidity cabinet with lighting?

A laboratory temperature and humidity cabinet with lights is a specialised piece of lab equipment designed to control temperature and humidity while also providing lighting for specimens or samples stored inside.

The addition of lights to the cabinet is handy for researchers who work with plants or other photosensitive samples. The light source can be adjusted to provide the optimal wavelength and intensity for growth, which can help to promote healthy plant growth and other research activities that require light.

What is Dew Point?

The dew point is the temperature at which dew (condensation) forms and is a measure of atmospheric moisture. It is the temperature to which air must be cooled at constant pressure and water content to reach saturation. Dew points are expressed as a temperature. Higher dew points correlate to higher moisture content, also known as absolute humidity.

The dew point represents the lowest temperature to which air with specific temperature and relative humidity (RH) can be cooled. At the dew point, air has a relative humidity of 100%, and additional cooling produces condensation rather than lowering the air temperature.

Do I need a water tank to supply water to the cabinet?
You only need a 25L/55L water tank if your cabinet cannot be connected to mains water supply. If mains water supply is not possible, 25L gravity and 55L pump water feed tanks are available to supply water to the cabinet. As a rule of thumb, a cabinet running at 90%RH will deplete a 55L water tank in approximately three days.
