The New York City Housing Authority is a major client of Molten Mechanical. We have been called on for projects large and small. Most notably NYCHA called on Molten Mechanical to assist in the restoration of services to Coney Island Houses following the Hurricane Sandy disaster. We are proud of our efforts during that time, restoring heat and hot water to the 1,400 residents in record time. Our performance was so good that we were asked to stay on and continue the restoration efforts in various other developments on Coney Island long after other contractors had left.

Other projects we typically undertake for the Authority are replacements of vacuum and condensate pumps, tank replacements and connection of fuel and steam lines for emergency boilers.

New York Foundling Hospital

New York Foundling Hospital’s building in New York City underwent a conversion from a full service children’s hospital to a mixed use building in 2012. Molten Mechanical was chosen as the contractor to¬† modernize the chiller plant. No small undertaking as the existing absorption chiller containing a solution of lithium bromide had to first be removed, then replaced with (2) 200 ton centrifugal chillers. Chiller and condenser pumps, automated controls and electrical systems were all replaced as part of this project.

Montefiore Medical Center

Montefiore Medical Center’s Moses Campus has hosted us on a number of projects. Due to our ability to work quickly, safely and with other trades we have been asked to perform over and over. In 2015 Montefiore began an upgrade of their MRI Suite from adding 3 units to their existing 2 MRIs. Molten Mechanical was selected to provide the welded stainless steel piping used to convey liquid helium from the MRI magnets to the Roof in case of an emergency.

Also in 2015 Montefiore undertook a re-purposing of an existing 12 story building currently used as a dormitory. In order to provide climate control for the new offices that will be incorporated in the building, Molten Mechanical erected a 100 Ton chiller on the Roof and ran new chilled water risers on the exterior of the building. Branches were brought into the building at each floor in order to provide future chilled water service as required.


North Central Bronx Hospital

The (5) tier, 15th floor Pressure Reducing Station at North Central Bronx Hospital provides usable steam for Operating Room climate control, humidification of patient wards and autoclave sterilization. The facility only allowed one tier to be worked on at one time and only for 8 hours a day. In other words, once a tier was taken down, it had to be put back into service by the end of the day. Not easy when dealing with 14″ high pressure steam lines! We were able to accomplish the job ahead of schedule leaving the facility very happy with the results.

Metropolitan Hospital

Metropolitan Hospital has been the scene of many upgrades over the years. Some notable projects : Modernization of the climate control equipment serving the Operating Rooms, Surgical and Neonatal Intensive Care Units; Upgrade of the Pressure Reducing Station, Ventilation and Humidification of the Renal Dialysis Center;  Heating and Air Conditioning for the NYC HHC EPIC Training Facility. Being a major New York City hospital every project is time sensitive and involves critical environmental systems. Just like working on a patient, there is no room for error on these projects.

Denihan Hospitality Group

In partnership with American Plant Maintenance, Molten Mechanical performed a full steam trap survey and replacement program for the Denihan Hospitality Group. Comprising (6) high rise hotel buildings with over 800 rooms this project involved testing, tagging and eventually replacing steam traps throughout the guest rooms, machine rooms and public areas of the facilities.

Pratt Institute

Working in historic buildings is never an easy task but Molten Mechanical passed this test with flying colors. Pratt Institute was losing tens of thousands of dollars per year in steam costs. By replacing failed steam traps in a campus-wide program Molten Mechanical has helped Pratt Institute put that money back into student programs. Our innovative solutions and industry partners helped us to maintain the integrity and look of the historically important steam distribution system and got the job done!

NYC Department of Education

The Edward R. Murrow High School building covers an entire city block and educates 4,000 students. Steam is a critical utility as it is used daily for both heating and cooking purposes. Molten Mechanical has provided needed repairs and upgrades to the physical plant. In 2004 MMMW replaced the #6 fuel oil preheaters for the main boiler plant. Although #6 oil has been phased out the steam plant remains in operation while burning #2 fuel oil and natural gas. In 2015 MMMW was called back to replace the decrepit vacuum pump with a newer model. Critical scheduling called for us to complete this work while the students were off for the Christmas and New Year holidays. The job went off without a hitch. The plant was put back on-line in three days and the students never knew anything was amiss. A+ for Molten Mechanical!
