Ambassadors of Fun


The past few months at Mulcahy have been filled with exciting news and events!

Our inaugural Walk the Pond event was a huge success! Six teams competed to complete the most laps in six weeks. While The Green Machines won, all teams enjoyed several happy hours, potlucks, plant night, and Cheesy Poof Olympics with Greg G. taking the crown.

Mulcahy employees also took part in charitable work. Volunteers had a blast clearing out invasive plant species at Hidden Falls Regional Park, and we collected seven large boxes of school supplies for the School Supply Drive for Keystone, helping many children at the start of the school year.

One of our most exciting announcements – Mulcahy was named one of Minnesota’s Top 150 places to work by Star Tribune! We celebrated with a pig roast. It was a day filled with lots of eating, a bags tournament, and a scavenger hunt.

Coming soon:

  • Company service directory (services, contractors, etc. recommended by our employees)
  • Food shelf volunteer opportunity
  • Chili cook-off
  • Halloween costume contest

Weishaupt Boiler – The Main Vein of Mercy Hospital


Steam Boilers – a Hospital’s Main Vein

In a hospital, the steam plant is a critical part of the infrastructure. The boilers provide steam for operations including building heat, domestic hot water, steam tables for kitchen use, humidification for surgical wards, laundry equipment, and for sterilizing both surgical equipment and medical refuse.

In 2012, Mercy Hospital’s central boiler plant had been limping along with outdated burners. Due to their age, parts were no longer available. After many visits from a local contractor to keep things running, it became clear it was time to replace the boilers.

New Technology Creates New Efficiencies

Burner technology has improved greatly over the last 25 years. In the past, burners relied on a single motor to drive linkages that attached to louvers on the air inlet and the shafts of the fuel valves. Burner setup was based on getting the best combustion for oil which dictated where the air louvers would be in relation to the gas valve. In older models, linkages wore and parts loosened. This wear and tear meant obtaining good combustion efficiency was very difficult.

The best combustion uses all of the fuel and oxygen. For safety, however, excess air is delivered by a constant speed fan. This excess air compensates for fluctuating amounts of oxygen as combustion air temperature changes.

To allow burner controls to set reliable, repeatable fuel/air mixtures over the entire combustion range, new burners incorporate linkageless controls with individual motors for each fuel-type and air dampers. New burners also make lower excess air possible by mixing fuel and air more efficiently. Measuring the oxygen amount in the flue and adjusting the combustion air damper controls the amount of excess air to a safe, low amount. It was paramount for Mercy to have a burner that maximized efficiency in this way.

Timeless Quality – Weishaupt Burners Provide Lifetime Savings

When it came time to decide on a new boiler system, Mercy had a choice between two options. The first was a burner from the installed manufacturer and the other for a Weishaupt burner, the largest burner manufacturer in the world.

Weishaupt developed the linkageless burner concept and was the first company to establish high turndown. These burners are the only ones with low excess air of 3% or less oxygen in the flue gas over the firing range. While both burners were proposed as linkageless, and had oxygen trim, the energy savings over the lifetime of the Weishaupt burner, along with the precision in its control, made for a more favorable investment. Mercy chose this solution and has witnessed efficiencies and little maintenance for the past six years. In fact, when an expansion was planned at the hospital, they asked to have Weishaupt burners installed and have had continued success in their operation.


Cooling Towers: Hunting for Energy-Efficiency & Low-Maintenance

Two summers ago, North Memorial Hospital (NMH), located in Robbinsdale, MN, presented vendors with a challenge. The hospital needed to expand their chilled water capacity while improving energy efficiency and reducing maintenance requirements. As a major medical provider in the area, reliability was also a primary concern.

Multiple vendors presented chillers and evaporative cooling tower options to the NMH maintenance staff. The extensive and competitive bidding process meant a final decision would come down to the fine details of efficiency, reliability, and cost-savings.

Maintenance Nightmares – The Baggage of Factory-Built Cooling Towers

Unlike smaller applications, NMH required large factory-built cooling towers. For these large horsepower applications, a gear drive is required as a speed-reduction mechanism. Unfortunately, gear drives pose many more maintenance issues than easy-to-replace belts used in smaller applications. Regular oil changes can be difficult and messy, the coupling arrangements require periodic maintenance, and eventually, the whole drive needs an overhaul or replacement – a massive endeavor usually requiring a prolonged shutdown and a crane.

Seeing that gear drives had long been the only option available for large factory-built cooling towers, it seemed NMH would have to deal with these same maintenance issues many others had faced for years… until Baltimore Aircoil Company (BAC) presented their Series 3000 cooling towers which used a new innovation – the Endura Drive permanent magnet motor.

Endura Drive System – The Perfect Solution

endura-fullThe Endura Drive system is a direct-coupled permanent magnet motor driven by a matched variable speed drive. With no speed-reduction mechanism, there are fewer parts to maintain and no energy loss associated with operation. The only maintenance required is an occasional greasing of the motor bearings.

With fewer breakdowns and higher energy efficiency, it was clear the BAC Series 3000 with Endura Drive represented the lowest cost of ownership option without sacrificing reliability and effectiveness. It was a no-brainer – the hospital staff awarded the bid to BAC.

Since the installation two summers ago, the cooling towers have provided the hospital reliable, efficient, and quiet operation without the pains of costly and difficult maintenance that gear drives bring.
