Delta-Therm
carries a full line of ambient and line sensing thermostats to
ensure dependable and accurate system control.
OTS-F5
Delta-Therm's OTS-F5 can be used
as an ambient sensing thermostat (with capillary coiled) or a
line sensing thermostat. It has a fixed set point of 40F. The
NEMA 4S (weatherproof and corrosion resistant) enclosure is gray
thermoplastic noryl. OTS-F5 comes with a fluid-filled,
nickel-plated bulb which may be used in air, gases, or liquids.
The maximum temperature for the sensing build is 140F. The
thermostat also features a 10' capillary.
applications: pipe
trace, tank trace, permafrost prevention, and snow melt

OTS-1A and OTS-2A
|
Delta-Therm's OTS-1A is a NEMA 4X
line-sensing thermostat featuring a watertight, dust tight, and
corrosion resistant die cast enclosure (OTS-2A is
ambient-sensing). The thermostat contains a calibrated reference
dial and tamper-proof adjustment for outdoor or indoor
locations. A liquid-filled thermal system, with its stainless
steel bulb and capillary, ensures a dependable and accurate
control system.
applications: pipe
trace and tank trace

 |
OTS-3A and OTS-4A
|
Delta-Therm's OTS-3A and OTS-4A
are explosion-proof and weatherproof temperature controls
suitable for indoor or outdoor use. The lightweight NEMA 4, 7, 9
and IP65 enclosure is made of die cast aluminum featuring gray
aluminum lacquer.
applications: classified area
pipe trace and tank trace

A319ABC-24-01 and
A319ABC-12-01
|
The A319ABC-24-01 and
A319ABC-24-01 are electronic line-sensing thermostats with a
single pole, double throw switch and LED indication. The A319
features an adjustable differential, enabling users to match
equipment cycle rate for a given application. The enclosure is a
NEMA 1 high-impact plastic suitable for surface or DIN-rail
mounting. To increase application flexibility and
serviceability, the A319 comes with a temperature sensor which
is interchangeable with optional sensors. Eliminates the need
for separate transformer, reducing installation time and cost.
applications: pipe trace, tank
trace, and permafrost prevention
|
|
A419
|
|
The A419 is a single-stage
electronic temperature control with a SPDT output relay. The
control features a keypad for programming and a liquid crystal
display for viewing the sensed temperature and the status of
other functions. A front panel LED indicates the control's
output relay status. The control has a set point range of -30 to
212F. The control operates at 120, 208, and 240 VAC.
The A419 control has heating
and cooling modes with adjustable set point and differential, a
lockable keypad, an adjustable anti-short cycle delay, and a
temperature offset function. The control combines remote sensing
capability and interchangeable sensors with electronic accuracy
in a NEMA 1, high-impact plastic enclosure suitable for surface
or DIN rail mounting.
applications: pipe trace, tank
trace, and permafrost prevention

|
A19ANC-1 and A19ANC-2
|
|
The A19ANC controls serve as
either line or ambient sensing thermostats designed for areas
where rainproof enclosures are required. The gasketed, rainproof
enclosure has a gray UL Listed outdoor finish.
Both models include a
liquid-filled element which is not affected by barometric
pressure. The thermostats have dependable, field-proven,
snap-action contacts with a heavy duty rating for inductive or
resistance loads.
applications: pipe trace, tank
trace, snow melt, and roof, gutter, and downspout deicing
|
|
E55A-E21BS
|
The Powertrace E55A-E21BS can be
applied as line sensing or ambient sensing thermostat. It is
designed to protect against dust, water, and rain. The enclosure
is NEMA 4, and covers are gasketed. The switching is dual SPDT.
The switch may be separated may be separated up to 100% of
range. Switches may be wired normally open, or normally closed.
The bulb and capillary are stainless steel and the fill is
non-toxic oil which is not affected by barometric pressure.
applications: pipe trace, tank
trace, and permafrost prevention

FL-1
|
Delta-Therm's FL-1 thermostat
provides comfort control for in-floor and under-floor electric
heat storage systems.
|
|
FL-12P and FL-24P
|
|
The FL12-P and FL-24P electronic
thermostats provide comfort control for in-floor electric
heating systems. The thermostat senses floor temperature from an
external thermistor sensor. Each thermostat features a 7-day
programming with up to 4 setting changes per day. The thermostat
will store two temperature settings. The thermostat has a
built-in GFCI. |
