Vertical pumps save space and energy
In 2018, the HVAC system at a popular Caribbean holiday resort suffered a series of failures and leaks, resulting in frequent downtime. An initial review determined that the existing pumps were the cause and had to be replaced.
The review also noted that the pumps were oversized, which affected system efficiency. With the resort occupancy rates near 95% for most of the year, HVAC performance and reliability are crucial, so managers decided to go ahead with an upgrade.
Because local rates for electricity averaged $0.28 per kilowatt-hour (kWh) at the time, the project represented an opportunity for the resort to reduce its energy costs as well as its carbon footprint. After assessing the HVAC system, Armstrong recommended Design Envelope Vertical In-Line pumps to replace the existing primary and secondary pumps.
The team at the facility was impressed by the space savings created by the Vertical In-Line design and noted that subscribing to the Pump Manager service, which provides alerts, alarms and performance analysis data, made it easier to track equipment status and performance and support optimal efficiency and occupant comfort.
“Since our hotel is located on an island, we need a system that’s easy to maintain. The performance reports and messages provided by the Pump Manager are very helpful. Plus, the team at Armstrong is always available if we have any questions,” explained the resort’s manager.
The upgrade project provided a simple payback of less than two years and saves over $170,000 annually. The management team at the hotel is very focused on reducing its carbon footprint, so the annual energy savings of 558,000 kWh are an important measure of success.
