Horticulture Solutions
from Water Treatment to Dehumidification Systems

Regardless if you are operating a greenhouse or a hydroponic venture, controlling plant optimum temperatures helps in maintaining good plant health and increasing growth & yield potential.

Toyesi’s heat pumps are designed to manage true reverse-cycle temperature control to help manage the ideal temperature for your irrigation water & options to manage space humidity & temperatures.

Typical Solutions Include:

  • Hydroponic water temperature control  – preset temperature control for NFT, DWC and other Hydroponic set ups.
  • Hydronic Greenhouse Heating – Heat pumps for circulation hydronic radiant greenhouse heating.
  • Energy Capture and Reuse – Space ventilation, heat recapture and stored for hydroponic root heating or hydronic radiant heating etc.
  • Dehumidification & Water Recapture – Assists in managing humidity levels, and recaptures space moisture for reuse. Helps prevents leaf rot and greenhouse mould build up.
  • Multi-Function PCVER System – Aquatic Water Temperature control coupled with Ventilation, dehumidification, Energy Recovery

Toyesi Transthermal Smart Technology

Toyesi’s Transthermal smart heat pumps are designed to manage true reverse-cycle temperature control so that you can meet the needs of plant root health and ideal optimum temperatures.

  • Australian designed & Australian made since 1989.
  • Easy to operate, economical to run & srviceable for life.
  • Built in Sydney, but designed so that your local specialist can install, maintain and service our equipment keeping down-times to a minimum.
  • Preset temperatures – set and forget and the heat pump does the rest.
  • Readily available local parts meaning NO long waits for overseas parts to arrive.
  • We work with industry specialist to ensure a turn key solution where possible.
  • We listen, we learn we improve with you and for you.

Importance or Root Temperature Control

Plants have an amazing ability to change respiration rates in the attempt to minimise the impact of changing ambient conditions. However, their achillies heel is their root systems.

Root systems of plants lack the same capability to regulate its own temperature, and if the root temperature drops or raises too high the roots cannot provide the plant with water and nutrients, which significantly can reduce plant growth and health.

In nature the soil is a great buffer to the changes in  ambient temperature, but in a hydroponic or NFT system the roots can become highly susceptible to ambient temperatures.

Depending on your set up, it can be impossible or impractical to control ambient temperatures all year round. However, by setting up your NFT system with a Toyesi Transthermal Smart Heat Pump you can maintain your nutrient rich circulation water all year round for optimum growth potential.

Effects of Temperature

  • Temperature can be an important and potentially limiting factor in growing plants in any NFT System.
  • Low Root Temperatures can hamper water & Nutrient uptake by roots.
  • High Root Temperatures can unduly stress plants and damage root systems.
  • Ideal Temperatures around 26oC water temperature will have amazing benefits – shorten germination times and speed up growth of seedlings.

So by using a Toyesi Reverse-Cycle heat pumps system you can maintain almost any desired ideal growth temperature all year round. Optimum growth temperatures with huge potential plant growth and yields.

Vegetables & Extending Seasons

Vegetables can be loosely grouped according to their growing season.

  • Cool Season Vegetables: Grow best when temperatures are between 10-20 degrees C or even lower. They include: broad beans, broccoli, Brussels sprouts, cauliflower, onions, peas, spinach and turnips.
  • Intermediate Season Vegetables: These are best between temperatures of 15-25 degrees. Include: beetroot, carrot, parsnip, celery, leek, lettuce, radish, silver beet.
  • Warm Season vegetables: Are grown best when temperatures are above 20 degrees C. Include: Beans, capsicum, eggplant, potato, sweet corn, sweet potato, tomato and cucurbits (including cucumbers, zucchini, pumpkins etc.)

So to extend the seasons is to control or mimic the temperature and light conditions of the seasons that the plants grow best in. Heating the roots, and controlling ambient temperatures is one of the best ways to achieve this.

Environmental Venting System

From plants, animals through to people, we all enjoy a level of coolness, warmth, sun light, water and food for basic survival needs and for creature comforts.

Heating or cooling buildings, pools and greenhouses are things many now take for granted. However, with increasing concern on running costs, the environmental impact (being Green) many people are looking at alternatives with the same of better results.

There are many ways to heat or cool such environments.

  • Gas heaters
  • Electric heaters
  • Air-conditioners
  • Fans
  • Hydronic heating
  • Evaporative systems
  • Heat Pumps
  • Chillers
  • Solar

Each type has its own benefits and pitfalls, and in some cases, several must be used and overlapped to gain the best and most economical running costs.

Also greenhouses come with other issues, such as lighting, managing humidity levels, venting out heat, then putting heat back in and much more.

Toyesi’s Energy Saving Solution

The PCVER System can be used as a stand-alone system within smaller greenhouses or stacked with other systems or other PCVER systems. The advantage of stacking the Toyesi PCVER system is that it will reduce overall heating requirements of the greenhouse and reduce wasted ventilated heat energy, captured for later use.

The PCVER Greenhouse System has several key functions and options.

  • Horticultural designed heat pump
  • Dehumidification
  • Clean condensate water for reuse
  • Improved ventilation & air flow
  • Energy capture, storage & recovery
  • Green option & Energy savings – lower footprint
  • Temperature control
  • Disease susceptibility reduction
  • Reduce overall running cost
  • Optional Benefits – Root zone heating, floor heating, hydroponic heating, Radiant space heating, Aquaponic water heating and cooling
