The Benefits of Factory Service:

An Absorption Chiller often is the largest significant operating asset in the building HVAC system.  It is also a significant energy consumer and typically represents a large portion of the building’s operating cost related to HVAC operation.  Ensuring and verifying that the chiller is operating within the proper application parameters, most buildings can save thousands of dollars a year as well as ensure that the chiller reaches it life cycle goals in an affordable manner.

A chiller that is not properly maintained or operated will result in unexpected repair costs and unreliable operation.  Broad U.S.A.’s intention is to offer a variety of maintenance options to compliment the owner’s expertise and time that the operators can dedicate to proper service, maintenance and operation.

Together as a team, we have found that most building owners will lower their operational costs as well as ensure that their chiller reaches its design life cycle goals.

Service Options To Consider:

  • Preventative Maintenance

Typically a preventative maintenance relationship is the most affordable contractual agreement between the owner and service provider. The number of visits can be tailored to fit your specific requirements so that cost can be kept to a minimum with the understanding that additional visits or additional requested service procedure can be procured at the owner’s request on a time and material basis based on discounted contract labor and material rates.

  • 24/7 Monitoring via the Internet

Broad U.S.A. has found based on customer feedback that this monitoring service is probably the single most useful tool for supporting our customers. It also is instrumental in providing proactive recommendations to ensure the lowest total cost of ownership.  Often minor adjustments can be made over the phone by collaborating with the onsite operator or superintendent responsible for the building operation.

  • Full Maintenance & Extended Warranty

For customers who do not want any exposure to risk or downtime, full maintenance with extended warranty coverage is highly recommended.  In essence, this extends the full factory warranty and any service procedures required for the life of the chiller at no additional cost.

Examples of Full Maintenance Procedures are:

Almost without question the “open tower condenser loop” of your building system should be cleaned at least once a year.  The cleaning of the absorber and condenser tubes with proper equipment and trained technicians will ensure that the tubes last for the life of the chiller.  This annual event will also pay for itself within a few months by lowering operating costs back to the original design conditions. A fouled condition can reduce heat transfer and lower operating efficiency.  Other heat exchanges should be evaluated on a case by case basis with regard to when and how frequently they should be cleaned.

Just like a boiler a direct fired chiller operation is a function of proper air to fuel mixture and burner operation.  This annual procedure will ensure that operating cost remains low and the burner will not have undesirable operational issues or an adverse effect on the environment.

This nondestructive electronic test can ensure that the tubes of the chiller are not deteriorating prematurely.  A tube that leaks can cause significant damage to the chiller and will stop the chiller from operating. The cost of this test is a small investment against larger preventable unforeseen expenses down the road.  Typical culprits of tube failure are poor or inadequate water treatment or improper flows through the heat exchangers.  Often your insurance provider will suggest this procedure be done to lower your premium as your chiller reaches the 5, 10, 15 and 20-year mark of operation.

This annual service is imperative to ensure the machine is operating within the design requirements of the operation of the machine.  The enemy of all absorbers is corrosion of the ferrous material inside the chiller which can occur if the inhibitors are not present in the lithium bromide solution.  This service can generate a great deal of information pertaining if any suspended solids are present which can affect performance, reliability and operating cost.  It the equivalent of getting your blood work at your annual physical.  The chiller might look great on the outside but this added information can allow us to make small recommendations to ensure that the chiller reaches its full life cycle without unexpected additional costs or repairs.

Often either the result of abnormal purge operation or the result of a poor LiBr solution report an absorber might require a leak check.  A leak check is done to insure that air is not leaking into the chiller even before it is detectable by the operator.  This proactive service procedure can potentially avoid more expensive procedures caused by the entrance of oxygen into the inside of the chiller. Without oxygen, corrosion cannot occur.

Should your chiller have been improperly serviced and perhaps too much inhibitor has been added over time we can restore the LiBr solution to the recommended levels to ensure proper and efficient operation.

Should the LiBr solution become dirty or fouled due to suspended solids, a modern absorber can clean itself up while operating.  This filter and service procedure will allow the LiBr solution to return to it optimum conditions for low operating cost and reliable operation.

Often improper cooling tower temperature control can lead to less than optimum chiller operation and potential crystallization.  A simple and easy way to remove this risk is to have our access and make modifications to the way the system is being controlled.  The PLC controller on the absorber is fully capable of providing proper total system control to ensure that the operating costs are kept low and nuisance trip outs to a minimum.

This training is available regionally through the year in North America or if desired we are happy to schedule specific training for your staff.  Whether you’re the owner or contracted service management firm our goal is to support your requirements for years of successful trouble-free operation.

Insuring & Maintaining the Chiller Vacuum Standard for Long Life Trouble Free Operation

  • The Benefits of Joining Procedure by a Factory Trained Service Engineer:

An Absorption Chiller often is the largest significant operating asset in the building HVAC system. Often due to jobsite or shipping constraints a chiller will sometimes ship in tow or sections under a protective nitrogen charge. A chiller that is not properly joined together can be a source of leakage or poor vacuum which can plague a units operation and adversly effect it total cost of ownership. Should you elect to join the chiller with your own staff we are happy to supervise?

  • Setting the Bar High on Standards

Broad Absorbers whether they are simple single stage or ultra high efficiency multi-energy two stage chillers all are designed to the same Stringent Vacuum Standard.  The passing test for the Broad standard helium detection test is 10-8 atmospheres of pressure per cubic centimeter of volume per second an industry best in class.

Tube material choice and the impact on longevity of the absorber coupled with a great modern design and good vacuum is what a modern absorber can deliver to your project.. Broad typically is providing higher quality materials such as “oxygen free copper”, CuNi and thicker walls to insure the chiller meets it 25 year life design cycle without unplanned and costly re-tubing common in other older absorption designs.

Contractor Services to consider:

  • Pre Start Up

CheckModern absorbers that utilize PLC controls have a variety of options regarding interface to the Building Automation System.  By meeting with the ATC contractor we can often provide coordination assistance to insure proper sequence of operation and safety devices are wired to insure worry fee operation.

Today BMS systems can access numerous point via Modbus, BacNet or Lon works interface available with Broad Absorption chillers. As a commitment to our customers Broad USA still recommend that you allow internet monitoring of you chiller thru a simple internet connection or 3G mobile phone line as it make start up and commissioning a much smother process and allows us to provide proactive diagnostics to your chiller to insure peak performance.

  • Leak Check

Often either the result of abnormal purge operation or the result of a poor LiBr solution report an absorber might require a leak check periodically..  A leak check is done to insure that air is not leaking into the chiller. This proactive service procedure can potentially avoid more expensive procedures caused by the entrance of oxygen into the inside of the chiller without oxygen corrosion cannot occur and the removal of non-condensable is key to keep you chiller operating at peak efficiency.
