Title: Understanding Corrosion in Electric Heater Element Evaporator Trays – Beyond the Blame Game

In response to the significant interest in my previous article on condensate corrosion in copper gas loop evaporator trays, I’ve received many questions regarding corrosion in electric heater element evaporator trays. While cleaning chemicals are often the go-to culprit, it’s essential to recognise that corrosion can stem from various sources. This article explores the causes of corrosion in stainless steel evaporator trays, supported by research from corrosion experts. I’ll address aluminium evaporator trays in a future article.

The tendency to blame cleaning chemicals oversimplifies the issue. Galvanic corrosion, anodic corrosion, localised …

Preventing corrosion in copper used in heat loop vaporiser trays requires careful consideration of several factors, including the environment, water chemistry, and material coatings or treatments. Copper is generally resistant to many forms of corrosion, but in the presence of certain conditions (such as acidic water, chlorides, or dissolved oxygen), it can corrode over time. Here are the most effective methods to prevent corrosion in copper heat loop vaporizer trays:

1. Control Water Chemistry
pH Control: Maintaining the water in a neutral to slightly alkaline pH range (around 7.5 to 9) can prevent …

In the intricate web of factors influencing retail operations, one often overlooked aspect is the drainage system. Yet, the impact of a poorly installed drainage system can ripple through every facet of a retail establishment, ultimately affecting the price of goods sold. From increased maintenance expenses to compromised infrastructure, the consequences are far-reaching and costly.
When it comes to drainage systems, proper installation is paramount. Inadequate planning or shortcuts during installation can lead to a myriad of problems down the line. One of the most immediate issues is drain blockage, which not …

Integral chiller cabinets have some apparent advantages over remotes, evaporative drainage is one of them, and using a hot gas loop seems a brilliant idea, but is it?
With many customers finding corrosion on the gas vaporiser pipe in condensate
evaporator trays, it’s logical to assume it’s the cleaning products being used, but is this
true? The same corrosion was found on cabinets less than a year old, that had never
been cleaned, so how can you account for corrosion on copper that has never seen a
cleaning product?
The well documented fact is, condensate water …

The discharge hose is a crucial link in the condensate pump system. It carries the removed water from the appliance to a suitable drainage location. It’s essential that the hose remains free of any obstructions or restrictions to ensure the smooth flow of water.
Condensate pumps play a pivotal role in maintaining the efficiency and functionality of chiller cabinets when gravity is not available. These simple devices, have unjustly earned a poor reputation in the food retail environment. In this article, we look at some of the reasons.
Understanding Condensate Pumps
Condensate pumps serve …

Dairy cabinet pumps, constructed with stainless steel, are designed for long-term durability and have a significantly longer service life compared to pumps made of other materials.
However, when a simple component failure occurs, these pumps are often discarded instead of being repaired or remanufactured. This is where remanufacturing comes in, offering significant advantages in waste reduction.
Remanufacturing extends the lifespan of used products through repair and upgrades, reducing the need for new manufacturing and minimising waste generation. By reusing and refurbishing existing products like dairy cabinet pumps, valuable resources such as energy and water are conserved, leading to a decrease in the …

When you step into a supermarket, you expect a cool, comfortable environment with fresh food on display. However, have you ever noticed water pooling on the floor near the chiller cabinets or the black and yellow absorbent strips? This is likely due to condensate drains that are not functioning correctly.

Condensate drains play a critical role in chiller cabinets in supermarkets by removing the moisture that builds up from the cooling process. However, if these drains become blocked, they can cause numerous problems. One of the most common issues is the buildup …

Recent events have brought refrigeration drainage issues into the spotlight, highlighting the need for proper maintenance, compliance with health and safety standards, and liability. This article explores the compliance standards and legislation governing HVACR drainage in food retail.

Compliance Standards and Regulations

Compliance standards ensure the health and safety, welfare, and convenience of a building’s occupants while conserving energy.
The Workplace (Health, Safety and Welfare) Regulations 1992 Reg 12, The Health and Safety at Work etc Act 1974 (HSW Act), The Management of Health and Safety at Work Regulations 1999 are the main legislation used in the event of a Health and Safety …
