Agriculture & Horticulture Climate Control

The Ventura range is a purpose‑built climate control solution designed specifically for greenhouses, grow rooms, agricultural buildings and animal environments. Using advanced air‑to‑air heat pump technology, Ventura systems provide reliable heating and cooling without the need for gas boilers or evaporative cooling. This allows growers to maintain stable temperatures year‑round, protecting crops from extreme weather, improving plant health, and supporting higher yields and faster growth cycles.

Ventura systems are engineered for versatility, with both ducted (T‑Series) and stand‑alone (G‑Series) configurations available. The T‑Series delivers long‑distance airflow through insulated ducts, making it ideal for larger greenhouses, poultry sheds or spaces where even air distribution is essential. The G‑Series offers multi‑directional nozzles and rapid installation, making it suitable for portable structures, smaller greenhouses, workshops, and grow rooms. Both ranges are built with robust metal construction, high‑quality components, and low‑noise operation to support continuous 24‑hour use in demanding environments.

Each Ventura unit is designed for energy‑efficient performance, delivering consistent temperature control while minimising operating costs. With heating and cooling capacities ranging from 5 HP to over 40 HP, the systems can be scaled to suit everything from small propagation rooms to large commercial greenhouses. Digital temperature control panels, MODBUS connectivity (G‑Series), and flexible installation options ensure growers can fine‑tune their climate with precision and reliability.

Overall, the Ventura system provides a complete engineered climate control solution for horticulture and agriculture. By combining heat pump efficiency, durable construction, and adaptable configurations, Ventura helps growers create optimal environments for plants, animals, and crops—supporting healthier growth, extended seasons, and improved productivity across a wide range of controlled‑environment applications.

Hydronic heating remains one of the most effective ways to maintain stable temperatures in commercial greenhouses. Large circulating pipe loops, buffer tanks and continuous hot‑water flow create an even, gentle heat that supports root development, reduces humidity swings and protects crops during cold snaps. Traditionally, these systems have relied on gas boilers, but rising energy costs and emissions pressures are pushing growers toward cleaner, more efficient alternatives.

For low‑temperature hydronic systems operating between 45°C and 55°C, Toyesi and Trident hot‑water heat pumps offer an ideal replacement for gas boilers. These units deliver consistent hot‑water output with far lower running costs, making them perfect for under‑bench heating, root‑zone heating and general greenhouse hydronic loops. Their efficiency and reliability make them a smart upgrade for growers wanting to reduce energy use without sacrificing performance.

When growers require high‑temperature hydronic heating, especially systems running up to 80°C, Thermace hot‑water systems step in. Built as two‑stage heat pump systems, Thermace units are engineered to deliver high water temperatures even in challenging conditions. With operating capability from  minus 12°C to 50°C ambient, they provide dependable performance in almost any climate, from cool southern regions to hot northern environments. This makes Thermace a powerful, future‑proof alternative to high‑temperature gas boilers.

Together, Toyesi, Trident and Thermace create a complete hydronic heating ecosystem for greenhouses of every size. Whether you need low‑temperature efficiency, high‑temperature performance or a full boiler‑replacement strategy, these heat pump systems offer growers a cleaner, smarter and more sustainable way to heat their facilities year‑round.

Precise water temperature control is one of the most critical factors in hydroponics, aquaponics and water‑based horticultural systems. Whether you’re managing nutrient solution in NFT channels, deep‑water culture beds, aquaculture tanks or root‑zone hydronic loops, even small temperature swings can stress plants, slow growth, weaken immunity or disrupt fish health. Stable water temperatures create stable biology — and that stability is the foundation of consistent yields, healthy roots and predictable system performance.

Toyesi’s water‑temperature solutions are built around high‑efficiency reverse‑cycle heat pumps and chillers, engineered specifically for horticulture, aquaculture and nutrient‑rich water environments. Unlike repurposed pool heat pumps, our Toyesi, Trident and Platypus units use titanium heat exchangers, corrosion‑resistant chassis and advanced control systems designed to handle fresh, salty and nutrient‑dense water. This ensures long service life, low maintenance and precise temperature control across a wide range of applications.

For small systems — backyard hydroponics, hobby aquaponics, research tanks and small hatcheries — the Platypus Mini provides compact, accurate heating and cooling in a single unit. With temperature control from 8°C to 40°C, Auto Mode, and titanium internals, it’s ideal for growers who need a simple, reliable, all‑in‑one solution. For commercial operations, the Trident range delivers industrial‑grade performance with capacities from 4 kW to 440 kW, scalable into multi‑stage systems for large farms, aquaculture facilities and high‑volume hydroponic operations. Every Trident unit is a heater‑chiller, providing full reverse‑cycle control to maintain a stable “dead‑zone” temperature range — heating when water gets too cold, cooling when it gets too hot.

Across hydroponics, aquaponics and horticulture, maintaining root‑zone and water temperatures is essential for plant health, nutrient uptake, fish welfare and overall system efficiency. Toyesi’s water‑temperature control systems give growers the ability to lock in the exact temperature their crops or species require — whether that’s 18–22°C for lettuce, warmer conditions for tomatoes, or species‑specific ranges for aquaculture. With Australian‑built reliability, long service life and precise digital control, our heat pumps and chillers provide a stable foundation for year‑round production and healthier, more resilient growing systems.

Some growing environments don’t fit the standard mould. Small grow rooms, dual‑purpose facilities, mixed air‑and‑water systems, and advanced monitoring requirements all demand solutions that go beyond traditional climate control. Our Custom & Speciality Projects division is built for exactly these situations — where off‑the‑shelf systems fall short and tailored engineering delivers the best results.

We work closely with growers, facility managers and consultants to design systems that match the exact needs of the space. Whether it’s a compact room requiring precise air control, a facility needing simultaneous water heating and air cooling, or a project that integrates climate data into a full IoT ecosystem, we engineer solutions that are efficient, reliable and future‑ready. Every project is built around the same principles: stable temperatures, low running costs and long‑term durability.

These speciality solutions cover a wide range of niche applications, including:

• PAS Split Systems for small grow rooms, cool rooms and micro‑environments
• PCVER Dual‑Function Systems for spaces needing water heating and air cooling at the same time
• IoT Smart Climate Technology for remote monitoring, automation and integrated control
• Aquaponic Temperature Solutions for systems requiring precise water stability for fish and plants

By combining advanced heat pump technology, intelligent controls and custom engineering, we help growers solve unique climate challenges that standard systems can’t address. Whether you’re building a specialised research room, upgrading a mixed‑use facility or integrating smart automation into your operation, our team delivers tailored climate solutions designed to keep your environment performing at its best.
