1. Product Overview
The Sigma Panel Radiator is an innovative approach in
hydronic architechural heating panels. With its totally
enclosed active heating element and a simulated
tubular facade, this unit provides the aesthetic beauty of
a steel panel radiator, with the capability of high water
temperature operation. This is accomplished by ensuring
that the exterior tube facade does not carry any water.
Instead, the water is carried by a high capacity heating coil
insulated from the exterior tubes of the facade.

2. The Basics
Sigma Panel Radiators are manufactured to give the
appearance of a Steel panel radiator with the advantage
of still being safe using high temperature water.
Over the years Steel panel radiators have been misapplied
using high hot water temperature in areas where the public
can touch the radiator. This can result in burns and
applications that violate building codes across North
America. Many building codes do not allow temperatures
to be above 140 °F in pipes. Utilizing a small safety factor,
the entering water temperature should not be specified at
greater than 135 °F entering water temperatures.
Even when consultants specify average water
temperatures of 125 °F or less, using a 20 °F delta T,
sometimes building operators will increase water temperatures on cooler days. This places the building and the owner
at risk of violating codes for high hot water temperatures.
With its totally enclosed active heating element and a
simulated tubular façade, this unit provides the aesthetic
pleasure as well as practical safety. This is accomplished by
ensuring that the exterior tube façade, unlike steel panel
radiators, does not carry any water at all. Instead the water
is carried by a high capacity heating coil insulated from the
exterior tube facade. This unit can also be used at lower
water temperatures.
The aluminum exterior does not reach temperatures above
125 °F even when steam or extreme hot water is applied
to the unit, ensuring safe operation regardless of outside
adjustments.
The Sigma Panel Radiator will comprise of oval shaped
tubes arranged in a Pedestal or Wall Mounted
configuration.

3. Design Considerations
The convector coils shall be tested at 250 psig and can
operate at a working pressure of 150 psig. The coils are fully
headered at each end and standard pipe connections of
½” NPT are provided. (optional ¾” NPT are available)
Unit shall be painted in a powder coat process. All painted
surfaces shall be cleaned and phosphatized in preparation
for powder coating. Paint thickness shall be 2 to 3 mils.
Sigma offer standard colours from our color chart, special
colors can be specified to match the architect’s request.
Pedestals will be supplied for field mounting of floor mounting version. Continuous joggle strip will be supplied for field
mounting of wall mount versions. Contractor to ensure that
the units are installed level and appropriate fasteners utilized
for respective mount surfaces.

CONCEPT
UNIT SPECIFICATION
The Sigma Panel Radiator Konvector is built with high
capacity heating element that has the capability of
both high water temperature and low pressure steam
applications.
The Sigma Panel Radiator Konvector will comprise of
flat oval-shaped tubes arranged in pedestal or wallmount configurations, as required. The tubes shall form
an architectural façade and shall not carry any hot
water. All exterior surfaces shall be painted with a baked
on powder coat process. All painted surfaces shall be
cleaned and apostatized in preparation for powder
coating. Paint thickness shall be 2 to 3 mils. For optional
colors refer to Sigma colour chart. Custom colours are
available.
Pedestals will be supplied for field mounting of floor
mount styles. Continuous joggle strip will be supplied
for field mounting of wall mount assemblies. Contractor
to ensure that the assemblies are installed level and
appropriate fasteners utilized for respective mount
surfaces. Optional overlapping accessories such as trims,
corners, and end-caps to be provided as directed.
The high capacity hydronic convector element shall
be manufactured of copper tubes and aluminum fins
and shall be tested at 250 psig and can operate at a
working pressure of 150 psig. The number of tubes, fin
size, and connection configurations shall be provided
to suit the supply and return locations as shown on the
plan drawings. The connections will be nominal ½”,
5/8”, or ¾” sweat connections, depending on element
configuration. Element length and quantities shall be
provided to suite the required capacities.
FLEXABILITY
The SRK concept of construction allows the flexibility
of various heating element configurations to suit the
capacity requirements of given assembly heights for wall
mount or pedestal mount applications.
