Disaster Invokes Change
On October 3, 1962, a boiler explosion
that claimed the lives of 21 people occurred at
a New York
Telephone
building in
Manhattan. This
disaster, caused
by an undetected
low water
condition, forever
changed the way all
steam boilers would be
manufactured and installed.
Not long after this tragic
event, New York Telephone
began investigating better
ways of protecting their
employees and property from
such hazards as low water conditions.
A Man with Ingenuity
At that time, Michael DeLeonardis
of Farmingdale, New York, was
experimenting with a new electronic
water level device for steam boilers.
He had developed his idea in Italy,
where he trained as a steam engineer
in the years before World War II. After immigrating
to America, Michael further refined his ideas
working on shipboard steam boilers with the
Brooklyn Navy Yard.
The Probe Principle
Michael’s idea was simple
but effective.
Using water as an
electrical conductor,
he designed a
control utilizing a
“probe” sensor. The electronic
control monitored the level of
the boiler water without the use of moving parts
that can wear and stick. A revolutionary time delay
mechanism was incorporated which allowed the
probe to be used in the violent water of a steam
boiler without short cycling the burner.
Hydrolevel is Born
Michael took his idea to New York Telephone.
They quickly recognized the advantages of his
design. In 1965 his electronic control was specified
for all New York Telephone buildings – and
Hydrolevel Company was born.
As with many inventors, Michael overcame
early opposition to his new device and soon other
government agencies, utilities and manufacturers
began specifying probe type cut-offs for both
commercial and residential boilers. It was Michael,
along with partner Russ Rymer and son
Dominick’s staunch defense of the time delay
feature, that paved the way for electronic cut-offs
used today.
Hydrolevel Today
Forty years later,
Michael’s inventive spirit
lives on. Today, Hydrolevel,
located in New Haven,
Connecticut, offers a full
line of innovative
products for boiler
protection and liquid
level control. The new
generation Hydrolevel
controls include CycleGard foam
compensating low water cut-offs, VXT
programmable water feeders, Safgard low
water cut-offs and multi-purpose liquid level
controls and HydroStat which combines multiple
functions, including temperature limit, low water
cut-off and fuel-saving boiler reset functionality
into a single control. Hydrolevel continues to
employ the latest technology to combine superior
features with performance and durability.
