Stop Replacing, Start Protecting with the DISCALSLIM® Deaerator

In the disposable modern world, the immediate reaction to an inefficient heating system is often the same – replace the old boiler with a new one. But what if the boiler isn’t the real culprit?

Replacing major components offers a temporary fix, but it’s a costly and wasteful game. The same issues, such as noise, corrosion, and plummeting efficiency, will inevitably resurface. Why? Because the problem often isn't the hardware itself, but trapped air in the system.

In this blog, we examine the DISCALSLIM® Deaerator, a smarter, more sustainable solution that addresses the root cause of system inefficiency.

 

The Silent Killer in Your Heating System

Air accumulation is the hidden flaw in many hydronic systems. As microbubbles circulate, they cause a cascade of problems:

  • Corrosion – Air leads to oxidation, corroding components from the inside out.
  • Noise – Gurgling pipes and noisy radiators are a tell-tale sign of air in the system.
  • Inefficiency – Air pockets cause localised overheating and prevent heat from transferring effectively, forcing your boiler to work harder.
  • Mechanical Damage – Pump seals and valves are vulnerable to damage from trapped air.

 

Continuous Protection with DISCALSLIM®

The DISCALSLIM® Deaerator offers an alternative solution to removing air from your system. Instead of repeatedly treating the symptoms, it eliminates the cause.

This innovative device is engineered for continuous air venting, down to the level of microbubbles. Ensuring the circulation of fully de-aerated water allows your entire heating or air conditioning system to operate under optimum conditions.

The result is a system free from noise, corrosion and damage, running at peak efficiency for the long haul.

 

Key Benefits at a Glance:

  • Maximised Efficiency – Deaerated water transfers heat more effectively, reducing the energy demand on your boiler and slashing ongoing running costs.
  • Extended System Lifespan – By preventing corrosion and mechanical damage, the DISCALSLIM® protects your entire system, including the boiler, pumps, radiators and valves, adding years to their operational life.
  • Silent Operation – Eliminate disruptive gurgling and knocking noises for good.
  • Universal Installation – Designed for easy installation on both vertical and horizontal pipes, with optional insulation shells to minimise heat loss.
  • Smart, Safe Operation – Its unique hydroscopic cap automatically releases collected air when the system is off, with a built-in safety mechanism that seals the valve in the event of a water leak.

 

Engineered for Performance

Built from robust, corrosion-resistant materials like technopolymer and brass, the DISCALSLIM® is a durable, set-and-forget solution. It’s rated for systems with a maximum pressure of 3 bar and temperatures up to 110°C, making it suitable for a wide range of residential and commercial applications.

 

A Smarter Investment for Your Wallet and the Planet

Choosing the DISCALSLIM® Deaerator is a technical, economic and environmental decision. You significantly reduce the scrap generated from premature boiler and component replacements while delivering substantial long-term savings to the end-user through lower energy bills and avoided repair costs.

FAQs

How does the DISCALSLIM differ from a standard manual air vent on a radiator?

Manual vents only remove large air pockets that have already accumulated and risen to the highest points in your system. The DISCALSLIM® is an automatic, continuous deaerator that works at the microbubble level. It actively scrubs the water of dissolved and trapped air as it circulates, preventing the air from ever accumulating and causing damage in the first place. It's a proactive, whole-system solution versus a reactive, localised fix.

 

Is the installation process complicated?

One of the key benefits of the DISCALSLIM® is its flexibility. It can be installed on either a vertical or horizontal pipe within the hydraulic circuit, making it suitable for a wide range of system layouts. A qualified heating engineer can typically install it without any major system modifications.

 

Does the unit require any maintenance?

The DISCALSLIM® is designed as a fit-and-forget solution. The only component that may require occasional attention is the hydroscopic cap, a simple and low-cost part. Its intelligent design ensures it operates automatically without needing manual intervention to release air.

 

How does the DISCALSLIM® contribute to sustainability?

By extending the life of your existing boiler and system components, the DISCALSLIM® directly reduces waste and the environmental footprint associated with manufacturing and disposing of new equipment. Also, by boosting energy efficiency, it lowers the carbon emissions of your building's heating system.
