Heating / Degassing / Cooling
Temperature Control Systems
| Aqua Systems pioneered the packaged hatchery heating system back in 1984. Over 100 units have been supplied worldwide. Systems can be provided with full waste energy recovery and a variety of energy sources, such as boilers, heat pumps and chillers to provide maximum operating efficiency. |
 |
The systems are designed as complete packages with all heat exchangers, pumps, pipe work, valves, degassing and controls. Units are available from 50l/min to 5000l/min. Accurate temperature is guaranteed to be within ± 0.5°C. |

System Operation
| The cold fresh water is pre-heated by the primary waste heat recovery heat exchanger. This pre-heated water then flows through the heat source exchanger to boost the temperature to the desired level. This is fully adjustable. Once the temperature is set the control system will maintain the desired temperature to within 0.5°C irrespective of incoming water temperature or flow rate. |

Back-Up and Servicing
| We pride ourselves on providing a 1st Class back-up service. As we build the systems ourselves, we have a team of technicians, all with experience in our products. They are available for installation, back-up and service work anywhere in the UK and overseas and are all experienced working in an aquaculture environment. |
Vertical These heaters are vertically mounted over the side of the tank. A slight disadvantage of heaters like this is that they require more depth to operate than L shaped heaters. L-Shaped These units are designed to sit on the bottom of the tanks and give a much more evenly distributed heat pattern than the Vertical units. |

Heat Budgets
| Accurately calculating the amount of heating or cooling that you need is a complicated business if it is done right. To size system accurately you must take into account the gains and losses listed below The amount of cooling energy required to cool an amount of water is calculated in the same way as the above, however, because of the way that air cooled chillers operate, the required amount of electrical input to the chiller is less. The percentage of electrical input energy required to achieve a given amount of cooling is dependant on the ambient air temperatures, ie. in temperate regions it is possible to get more cooling per kW electrical input than in tropical regions. The calculation of an accurate heat budget is important if your temperature control system is going to perform to it's design expectations. The main heat gains and losses in systems include: |
Heat Gains
 |
Solar gain from the sun on water, tank and building surfaces. |
|
Heat gain from ambient air to water, when ambient air is warmer, both directly into the water and through tank walls etc.. |
|
Heat from pumps, UV and other powered equipment within the systems. |
|
Heat production by the fish as they metabolise their food (even though the fish are cold blooded, they still add a lot of heat to the environment), which can build up in recirculation systems. |
Heat Losses
|
Evaporate losses |
|
heat loss from water to ambient air, when ambient air is colder, both directly from the water and through tank and building surfaces. |
|
Removal of fish from system |
To calculate the kW heating required to raise a flow of water by a set amount, use the following formula:
