walk in freezer

Globalization has brought about a radical change in the lifestyle of people around the world and the effect can be felt most in the accessibility of products.

Now, fresh exotic fruits from as far as California are available in the arid regions of the gulf.

Transportation and storage facilities have also undergone changes to meet the growing demand. In this direction, commercial coolers are a notable development.

A cooler, as the name suggests, is essentially a container with cooling facility and has become an important part of the food industry.

There are majorly two types of, namely a walk in cooler and a freezer.

Where as the first one cools the contents, the latter provides sub-zero temperatures and freezes the items inside.

Walk in freezers are used mainly for storing big amounts of different types of meat, whereas coolers are used for storing flowers or delicate fruits that require mild cooling.

A combination can also be used according to specific needs.

All these cooling devices are manufactured using state-of-the-art technology and are available in standard sizes. However, upon order, a custom made cooler can be built for customers.

The cooler cools using a condensing unit and an evaporating coil, where liquid gas is passed inside and then vaporized thereby causing a cooling effect.

While buying a cooler, the basic questions that have to be considered are, how much storage space we need, and do we have pace with walk in freezer ventilation and drains to accommodate the cooler. 

Many companies now offer personalized services where representatives will inspect the space to offer and advice on the type of cooler that can be used and how to effectively reduce the operating cost. 

Walk ins are generally made of prefabricated panels of aluminum, stainless steel or any other high density fiber and lined with urethane insulation. 

Another new material, G 90 galvanized, for the outer skin is inexpensive, high tensile strength and is resistant to corrosion and dents. Other major insulators are polyurethane and polystyrene. 

The price of the cooler completely depends on the size and the type of insulation chosen. On inquiry, a drawing of the made according to the specification of the client. 

After inspection, the final manufactured and installed. Major companies also offer warranty for the compressor and the coil that can be replaced later in case of faults.

Unless the replacement carries third party certification validating its suitability and compliance with lighting regulations, boaters should assume the fixture will not be acceptable.

At the end of the day though, the only persons responsible for maintaining compliance is the boat owner and operators, not manufacturers.

In order to meet compliance with navigation lighting regulations, lights must be tested by an approved testing group to ensure they meet brightness, visibility, color, corrosion and operating temperature requirements.

Lights must properly visible from the correct angles, and they must meet nautical mile requirements as well. Since bow lights and similar devices usually contain two colors which are intended to be separately visible from a specific range of angles in order for other boaters to be able to determine the vessels position and heading in relation to their own.

Improperly designed or installed lighting can alter these angles or reduce the overall visibility distance creating an unsafe condition.

In order to meet these requirements incandescent navigation light fixtures use housings and reflector assemblies that are designed specifically to work with the 360 degree radiance of the incandescent bulb.

They collect and focus the light from the incandescent bulb and distribute it in such as manner as to produce the highest possible brightness while achieving the correct angle of visibility.

LEDs on the other hand do not radiate light the same way. LEDs radiate light only over one portion of their surface, which results in a greatly reduced angle of radiance, oftentimes as small as 120 degrees.
If installed in a fixture or housing designed to work with a bulb producing 360 degrees of radiance, the result can be greatly reduced angle of visibility and much lower brightness.

The safest route for boaters looking to ljusskyltar upgrade to LED navigation lights to take is choosing dedicated LED fixtures that have been designed around the unique characteristics of the LED and ensuring these fixtures have been certified to meet Coast Guard requirements.

Besides ensuring better compliance and safety, new fixtures will allow boaters to realize much better savings and reliability as new fixtures will most likely be constructed of more durable materials and carry a warranty that covers the entire fixture rather than just the upgrade lamps alone.

The potential for safety issues and possibility of citations should an inspection reveal an upgrade is not in compliance far outweighs the small savings to be had from attempting to retrofit LEDs to existing fixtures.

In all reality, in most cases installation of a new fixture is more easily accomplished as well and leaves less room for installation errors and mistakes that could potentially damage the replacement or reduce its useful life.
