Vertical Farming Company


The Challenge –

Design a system to closely control the temperature and humidity levels of the vertical farming facility


The Solution –

A temperature control system which combines coils, chiller, and a tank with a variable speed pump set

Vertical farming offers a sustainable alternative to traditional methods of growing crops. It developed in response to challenges that conventional farmers were facing. It aims to produce higher quality, lower cost, pesticide free produce, reducing food waste and environmental impact. Here’s how Aqua helped with a temperature control system for a vertical farming application.

Situation

The vertical farming concept is effectively indoor farming, with everything carefully designed and monitored to ensure optimum growing conditions. Variables such as light, temperature, humidity, irrigation, and air composition are precisely controlled, and the process is pesticide free. The crops themselves are grown in vertical, stacked layers so footprint is kept to a minimum.

Aqua were tasked with designing a system to closely control the temperature and humidity levels of the vertical farming facility. Ideal growing conditions need to be simulated inside the farm so that resulting crops are both plentiful and high quality.

Solution

Our in-house design team created a system which combines coils, chiller, and a tank with a variable speed pump set. The chiller supplies chilled water to the coils. As the ambient air goes across these coils, the air temperature reduces and the humidity increases, to the required set point.

Results

Aqua have designed & supplied this solution, both in the UK and overseas. “It’s great to see how our cooling technology can be deployed in such a cutting-edge industry” explains Aqua Area Sales Manager, Mark Hopper.

“The potential vertical farming has to really make a difference with the agriculture and food sectors is quite astonishing.  I’m proud that Aqua have been involved in such an innovative & sustainable project.”

Aqua have also developed a pump skid version of the system for the client’s US site. The skid is effectively plug & play format, just needing to be connected to the chiller, which the client purchased locally. Ironically, buying this element of the equipment from Aqua helped them reduce costs by 50% and cut lead time from 14 to 6 weeks when compared to purchasing locally. It also enabled the client to finish their project on time, so avoiding further financial implications.

Farming & Food Processing Client In The East Of England


The Challenge –

Design A Reliable, Energy Efficient Cooling System


The Solution –

Complete System Design

When a fresh produce company was looking to replace their ageing chiller equipment, energy efficiency, reliability and ease of maintenance were at the forefront of their mind when it came to selecting their replacement cooling system.

Based in the East of England, our client has been growing, harvesting, and processing potatoes and root vegetables such as onions, carrots and parsnips, for over 100 years. They pack their own produce daily for distribution across the UK and further afield, as well as packing for other retailers.

Their factory had expanded over the 15 years so much it left the chiller on the roof with the only access being a man-way or 25 metre reach crane. Good news for the company but bad news for the chiller unit!

Aqua’s design team proposed an entirely new cooling plant for the factory which would provide cooling for all areas of the process – from the initial washing and cleaning of the vegetables right through to keeping the packed produce stored at exactly the right temperature before despatch to the retailers.

Our solution provided run and standby capacity by incorporating two chillers into the system, rather than just one. This gives built in redundancy with every component (including the evaporators) – in the rare event that a component should ever fail. It also focused on energy saving, utilising our range of Aqua Pro+ scroll compressor fluid chillers which are extremely efficient.

The system feeds chilled water at -5°C and operates on 30% monoproperlyne (food safe) glycol. The units were also positioned on site to ensure ease of accessibility for routine maintenance.

Full specification included:

  • 2 x Aqua Pro+ chiller units
  • Duplex pump skid
  • Inverter controls
  • Monoproperlyne (food safe) glycol
  • Full system design
  • Weir tank
  • BMS System

With maintenance issues resolved and a system harnessing state of the art cooling technology, our client will be harvesting the benefits for years to come!
