Heathland Group has introduced significant engineering upgrades across the OxiAir® range, enhancing performance, efficiency and specification clarity for professional water management projects.

The updated OxiAir Shallow®, OxiAir HD® and SolarAir® systems provide improved dissolved oxygen transfer, optimised airflow calibration and expanded depth capabilities — delivering robust solutions for ponds, lakes and reservoirs across the UK and internationally.

Designed and manufactured in the UK, the enhanced OxiAir® range continues to set the benchmark in diffused aeration technology.

Advanced Diffused Aeration for Oxygenation and Destratification

All OxiAir® systems operate using calibrated bankside compressor technology, delivering controlled airflow to diffuser membranes positioned on the bed of the waterbody. Microbubble diffusion ensures:

• Increased dissolved oxygen (DO) concentration
• Full water column circulation
• Reduction of thermal stratification
• Release of noxious and trapped gases
• Improved ecological balance

Diffused aeration remains one of the most energy-efficient and environmentally responsible methods of lake and reservoir management.

OxiAir HD® – High-Performance Deep Water Aeration (Up to 30m)

The upgraded OxiAir HD® system is engineered for demanding applications requiring deep water aeration and large-scale circulation.

A key enhancement in the new OxiAir HD® range is the introduction of an improved super cooling system, designed specifically to ensure maximum efficiency and long-term reliability during periods of high ambient temperature.

This upgrade improves thermal management within the enclosure, helping protect compressor performance and supporting consistent airflow delivery during summer conditions — when dissolved oxygen levels are often at their lowest and aeration demand is highest.

Technical Enhancements:

• Operating depth range: 0.5m to 30m
• Depth-dependent circulation rates for optimised destratification
• Airflow options from 6,780 lph to 27,120 lph
• Dissolved oxygen transfer rates up to 2,712 lph per metre depth
• Low operational noise levels (<31dB – <36dB at 1m)
• Depth-dependent power consumption scaling
• New super cooling system for improved efficiency and reliability in hot weather

The HD range incorporates high-efficiency compressors housed within durable, weatherproof enclosures. Stainless 316 manifolds and check valves ensure long-term reliability, including winter operation.

The refined enclosure configurations now align precisely with diffuser quantities, improving installation planning for contractors and civil engineers. Recommended base dimensions are clearly specified to assist with groundworks and site preparation.

Applications include:

• Reservoir destratification
• Commercial fisheries
• Golf course lakes
• Large estate lakes
• Irrigation storage reservoirs
• Industrial water bodies

OxiAir Shallow® – Energy-Efficient Aeration for Ponds and Lakes up to 2m Depth

The OxiAir Shallow® system continues to provide high-efficiency aeration for water bodies up to 2m deep, with improved technical presentation of circulation and airflow metrics.

Core Performance Specifications:

• Scalable diffuser configurations (2–8 diffuser models)
• Combined circulation rates up to 5,311,200 lph at 2m depth
• Airflow range: 4,800 lph – 15,000 lph
• Power consumption from 0.05kW
• Extremely low operating noise

Designed as a plug-and-play lake aeration system, OxiAir Shallow® offers simplified installation with minimal servicing requirements (typically 18–24 months).

Ideal for:

• Amenity ponds
• School and university lakes
• Holiday park water features
• Fisheries and estate ponds
• Residential lake management

SolarAir® – Off-Grid Sustainable Aeration Technology

The upgraded SolarAir® system provides renewable-powered aeration for remote or environmentally sensitive locations.

Recent enhancements across diffuser performance and airflow calibration improve oxygen transfer efficiency while maintaining zero mains energy consumption.

Solar Air remains a preferred solution for:

• Remote ponds
• Conservation areas
• Wildlife reserves
• Off-grid reservoirs
• Sites with restricted electrical infrastructure

By combining solar generation with efficient compressor technology, Solar Air reduces operational costs while supporting long-term water quality management.

Engineering Improvements Across the OxiAir® Range

The latest technical upgrades focus on performance optimisation and installation precision:

• Refined airflow calibration across all diffuser quantities
• Improved DO transfer data transparency
• Enhanced enclosure durability
• Expanded depth capability (HD range)
• Clearer specification metrics for consultants and engineers
• Consistent stainless 316 component construction
• Wireless remote activation (HD range)
• New super cooling system for OxiAir HD® enclosures

All systems continue to eliminate electrical components within the waterbody, ensuring maximum safety and compliance.
