<div style="background: white; line-height: 12.4pt; margin-bottom: 12.0pt; margin-left: 0cm; margin-right: 0cm; margin-top: 0cm; text-align: justify; vertical-align: baseline;">
<span style="font-family: "Calibri","sans-serif"; mso-ascii-theme-font: minor-latin; mso-bidi-font-family: Tahoma; mso-hansi-theme-font: minor-latin;">Restrained spring
mounts are isolators that provide <a href="http://www.andrehvac.com/">vibration isolation for mechanical systemsand equipment</a>. These isolators are designed in a way to limit vertical and
lateral movement of the top support plate caused by equipment operation or wind
loading. The uniquely-engineered springs are designed to provide maximum
isolation to the mechanical equipments. <o:p></o:p></span></div>
<div style="background: white; line-height: 12.4pt; margin-bottom: 12.0pt; margin-left: 0cm; margin-right: 0cm; margin-top: 0cm; text-align: justify; vertical-align: baseline;">
<span style="font-family: "Calibri","sans-serif"; mso-ascii-theme-font: minor-latin; mso-bidi-font-family: Tahoma; mso-hansi-theme-font: minor-latin;">There are mainly
two types restrained spring mounts namely open restrained spring mounts &
closed restrained spring mounts. <o:p></o:p></span></div>

is designed specifically for applications where transmission of low frequency
machinery vibration to a building structure must be reduced to avoid physical
damage or nuisance to the occupants. It is a low frequency mounting designed to
limit vertical movement on equipment such as cooling towers and chillers etc.
Applications located at roof level can be successfully mounted on ORS units as
any movement caused by high wind loads will be limited. Equipment which
contains large volumes of liquid will benefit from installation on ORS
mountings because during “draining down” upward movement is restricted thus
avoiding damage to pipe work and electrical connections.<o:p></o:p></span></div>

<span style="font-family: "Calibri","sans-serif"; mso-ascii-theme-font: minor-latin; mso-bidi-font-family: Arial; mso-hansi-theme-font: minor-latin;">As compared
to rubber mounts, spring mountings have greater static deflection resulting in better
isolation efficiency. This makes them more suitable for critical applications, especially
for mechanical and industrial equipment which have low disturbing frequencies.
Spring mounts come in a wide range of deflections offering maximum load, so
that the level of isolation can be accurately selected for each application.<br /></span><span class="bodytext"><b><span style="font-family: "Calibri","sans-serif"; mso-ascii-theme-font: minor-latin; mso-bidi-font-family: "Lucida Sans Unicode"; mso-hansi-theme-font: minor-latin;"><o:p></o:p></span></b></span></div>

<span style="font-family: "Calibri","sans-serif"; mso-ascii-theme-font: minor-latin; mso-bidi-font-family: Arial; mso-hansi-theme-font: minor-latin;">Closed
spring mounts are used beneath mechanical equipment, either alone or in conjunction
with inertia bases. They are installed with the purpose of minimizing the
transmission of noise and vibration to the building structure and providing a
rigid lateral support. They are suitable for indoor and outdoor mechanical
equipment isolation with lateral loads and minimal to no change in operating
weight. They are mainly used in mechanical equipments such as fans, pumps, air
handling units, booster sets, etc. These instruments offer an economic solution
to any kind of vibration problems in industrial or mechanical equipment. <br /><br /><o:p></o:p></span></div>

Mounts are supplied with a housing that restricts vibration and noise. These
equipments are useful especially when subjected to any wind loading or changes
in weight during maintenance. These isolators include welded housings designed
to limit vertical and lateral movement of the support. Restrained <a href="http://www.andrehvac.com/spring-mounts-c-5.php">Spring Mountscome in a wide variety of ratings and spring deflections</a>. They are encased in housing
with adjustable limit stops. When set correctly, the springs will provide
appropriate isolation. But in case the
equipment changes weight significantly due to any fluid drain during
maintenance or moves due to wind load, prevent the spring from moving
excessively. Restrained spring mounts are applications that include indoor and
outdoor mechanical equipment isolation, typical equipment may include cooling
