Innovations in Maintenance Technology

Facility managers with chillers and heat exchangers in their buildings know that a big part of routine maintenance is merely keeping the equipment clean. Cleaning the internal components, cleaning the housing, and even washing down the work area might be a messy and tedious job, but it’s necessary to ensure the proper function of the HVAC system. Clean equipment simply runs better and breaks down less frequently.

Over the years the complexity of HVAC equipment has increased, but many basic maintenance tasks like cleaning haven’t changed very much. Luckily for technicians, the tools needed to perform this work have improved, and dirty jobs like cleaning, pressure washing, or descaling can be completed faster than ever before.

Infographic-Products for Cooling Tower Health

A neglected cooling tower can lead to lower efficiency, shorter equipment lifespan and even Legionnaire’s disease outbreaks.  As such, cooling tower maintenance is a must for any proactive facility maintenance professional. ASHRAE Standard 188-2015 is a good resource to use when developing a maintenance and emergency cleaning plan, but where to turn to for equipment? Check out this helpful infographic for some of Goodway’s best products and chemicals for cooling tower maintenance.

Mission Critical Cooling: Focus on Data Centers

A 2016 report by the Ponemon Institute studied 63 data centers across the United States and calculated that the average cost of a large data center outage is $740,357. That astounding number probably makes IT professionals and data center maintenance staff a little nervous. No one wants to be the person who made a mistake that cost the company $740,357! Businesses that cannot keep data centers online also lose customers, costing the company even more money. Finally, there is the high price to rebuild their reputation and bring customers back. The pressure to keep data centers up and running has never been so high.

Coil Corrosion Causes and Reduction

Air conditioning manufacturers have been struggling with a serious problem the last several years; a problem that has left homeowners and small businesses across the country without reliable air conditioning and has led to at least three class-action lawsuits in the United States and Canada. The problem is pitting, corrosion, and eventual failure of copper evaporator coils in residential and light commercial air conditioning units. The HVAC industry is changing its processes in response.

An air conditioning unit works by moving pressurized refrigerant between an outdoor condenser coil and an indoor evaporator coil. Because evaporator coils are inside a building and protected from the elements, it would seem that evaporator coils would last a lifetime safely hidden away in an attic or closet. But it is precisely because the evaporator coil is sealed away so tightly that coil corrosion is becoming a problem.

Heat Exchanger and Boiler Maintenance: Chemical Descaling

Have you ever ironed a pair of dark pants only to have small white flakes fall out of the iron’s steam holes and make white streaks across your clothes? This is especially a problem in older irons that have never been cleaned. Your iron is in many ways like a commercial steam boiler. After a long time making steam, a boiler can clog up with white flakes and get trapped in the boiler system. This white buildup in both the steam iron and the boiler is a layer of calcium and other minerals called scale, or sometimes limescale. As the water evaporates, the minerals in the water don’t turn into steam when the machine is in use; they are left behind to form scale inside the equipment.

As annoying as those little white flakes are for your dark pants, imagine what those deposits do to the heating elements of large industrial equipment like boilers and heat exchangers. On some equipment, the scale buildup can be inches thick. An inch, or even a much thinner layer of scale is more than an annoyance, it’s a serious maintenance problem that diminishes system efficiency, reduces heat transfer, and increases operating costs. Just like maintaining and cleaning your steam iron, facility managers have to do the same for their heat exchangers and boilers.
