Les types et l'importance de bonne nuit de couverture en tissu

Q: What is unique about Econofrost’s night cover fabric?

A: What sets Econofrost apart from other night covers is it’s woven aluminum perforated fabric which is bonded with PVC to give it strength. It is also coated with a fire-retardant transparent film which exceeds 94HB (horizontal burn) restrictions.


Q: Quels sont les avantages de l'utilisation de ce type de tissu?

A: tissu tissé d'aluminium a la plus forte réflectivité (capacité à dévier le rayonnement et de la chaleur) et les plus basses valeurs d'émissivité (le tissu ne pas absorber ou de conduite de la chaleur). Comme cela est empêché par suite de l'air chaud du magasin et de la lumière à partir d'entremêlement le déversement d'air froid qui circule à l'intérieur de vitrines réfrigérées.

Comparing night cover fabrics

Q: Quel est le but des perforations? Et les stores produisent non perforés?

A: Humidity levels in grocery stores are often very high compared to the inside of a refrigeration display case, which can cause condensation build-up. The perforated fabric standard to Econofrost night covers, allows condensation to evaporate regardless of whether the night cover is up or down.

For produce cases which may or may not have misting systems, we have designed a night cover series without perforations. The Econofrost 9000 series NP (non-perforated) enables open display wet rack produce cases to be closed at night and allows for maximum energy savings in the produce department. The produce department has one of the highest rates of shrinkage so installing night covers makes the most sense. However, specific humidity levels are important in these cases and the BTU requirements are different than other open refrigerated display cases. The NP covers are just meant for produce cases with or without misting systems and where water content may vary.


Q: Comment est-il facile à nettoyer le tissu et que dois-je utiliser?

A: The Econofrost brand of night covers are really easy to keep clean and require little to no servicing. If you need to clean the fabric, a light solution of liquid soap is all that is required. Abrasive detergent or commercial cleaners are not advised.

Q: What is the R value of Econofrost night covers?

R: Il n'y a vraiment pas de réponse. En raison de la faible épaisseur du matériau, il est pratiquement impossible de tester les valeurs de R du tissu en utilisant des pratiques normales d'essai (test de la valeur de R se fait habituellement sur des matériaux épais comme isolant BATT). D'autres entreprises peuvent tenter d'appliquer une valeur R à leurs couvertures de nuit, mais les méthodes d'essai actuelles ne supportent pas.


Questions sur l'installation et nuit Produits personnalisés couverture

Q: Do I have to purchase Econofrost night covers as a retrofit option or is there a factory model?

A: For most cases already at the store level, a retrofit cassette is the preferred option. For a new case being ordered direct from the original case manufacturer, you can specify to have Econofrost installed. There are a select group of OEM’s who currently install Econofrost night covers in their cases for their grocery store clients.


Q: I’ve seen other night cover installs with many open gaps between each night cover unit, how is Econofrost any different?

A: Econofrost night covers also have small gap or openings that are visible when two or more units are installed side-by-side. In general, they represent an insignificant loss of energy as cold air tends to move downward and the openings allow the unit to breathe however if a retailer has no option but to install 4-foot units then the number of stop gaps increases and it can counteract the purpose of having night covers.

That is why we manufacturer longer length units and recommend retailers install the biggest length they could use. In addition, using 8-foot cassettes helps retailers cover more space with less number of units which also means less units to operate and service over time.


Q: Quelles sont vos tailles standard et longueurs de tissu?

A: At present we stock standard linear lengths of 4-foot, 6-foot and 8-foot cassette units in our retrofit models. Our electric motor driven blinds also offer a 12-foot unit. Please note, we accept custom orders and we can manufacture a variety of sizes.

The fabric length of our standard models measures 80 inches which easily covers a cooler case opening of 78″. For our electric units, standard fabric vertical length is 15-foot and 12-foot linear length.

Q: Que faire si je besoin d'une longueur de tissu plus ou une unité plus petite?

A: If you need longer fabric length we can most likely accommodate your request with a custom order. We can provide custom motor blinds with a maximum vertical fabric height of 20 feet and a maximum linear length of 20 feet. The smallest sized cassette unit we can provide is 27.75″ linear length.


Q: How do I determine whether I should use 4-foot, 6-foot or 8-foot units?

A: If you have a consecutive run of cases, the goal would be to incorporate as many 8-foot units as possible. Using 8-foot units in a store environment has three major benefits: First, it is less costly; one 8-foot unit is less expensive than 2 X 4-foot units. Second, it provides better energy savings; less gaps between the fabric of each night cover means improved performance. Third, less labor; when you use 8-foot units you use half the number of night covers to enclose a lineup of cases and therefore you save on time required to pull-down and retract the night covers each night and morning.

Econofrost provides a viable solution for closing these wide island cases at night.


Q: Après avoir installé la nuit couvre mes cas de viande, je devrai régler mes commandes du thermostat?

A: A self-serve meat case will typically have a discharge air temperature of about 22° to 24° F in order to ensure the product holds constant at or near 32° F. Since the discharge air temperature is so low, it is important to closely monitor the case once a night cover is installed. If the case is controlled by a thermostat or electronic evaporator pressure regulator valve (PEER Valve), La température du boîtier (température de l'air de décharge) ajustera automatiquement lorsque les couvercles sont tirés vers le bas et il n'y a généralement pas d'autre surveillance ou les ajustements nécessaires.

Covering the display case with Econofrost creates a thermal barrier between the product inside the case and the ambient store air. It ensures the product temperature comes down to discharge air temperature. If the display case is controlled with a EPR mécanique Valve, Alors il ne peut pas ajuster automatiquement et en tant que tel, il y a un gel possibilité se produira.

To ensure this does not happen, a night-time temperature setback is suggested. A night-time temperature setback is done by the refrigeration service technician – and the amount of adjustment depends on each refrigeration system. We suggest trying 1° F to start. For example, if the case discharges at 22° F, the technician may adjust the mechanical EPR Valve to 23° F and monitor it from there.
