Island Freezer Guide: Arc, Flat, Deep & Combo Types

Un island freezer is an open-top, sliding-lid display freezer designed to sit as a standalone unit or connect with others to form a continuous frozen-food aisle. The SLS line splits into four structural sub-types — arc, flat, deep, and combo — each built for a different display depth and temperature range, not just a different shape.

What Is an Island Freezer, and How Do the Four Sub-Types Differ?

Most retail listings for this category group everything under one “island freezer” heading and let the photo do the explaining. That works for a single storefront purchase. It works less well for a distributor speccing multiple SKUs for a chain rollout, where the shape of the lid and the depth of the well change how much product fits and how it’s merchandised.
Senlis makes four island freezer sub-types, each tied to a specific model:

• Arc Island Freezer (SLS-YD1200) — curved cabinet profile
• Flat Island Freezer (SLS-PD1200) — flat-top display well
• Deep Island Freezer (SLS-SD1400) — deeper storage cavity
• Combo Island Cabinet (SLS-ZD1860) — the largest footprint, built for mixed-category display

Arc, Flat, Deep, or Combo: Matching Freezer Type to Store Layout

The naming isn’t decorative. Arc-profile freezers are common where visual merchandising matters more than raw volume — the curved top reads as more open when a shopper walks past. Flat-top units trade some of that visual openness for a squared-off well that stacks bagged product more predictably. Deep units hold more per square meter of floor space, which matters for convenience stores working with tight aisle widths. Combo units are the widest of the four, sized for supermarkets running mixed frozen categories — ice cream next to frozen vegetables — in one connected run rather than two separate cabinets.

SLS-YD1200 to SLS-ZD1860: Specs at a Glance

All four share a copper pipe evaporator, LED lighting, and a night curtain for keeping cold air in overnight. Lid construction is listed across the line as curved sliding glass, flat glass cover, or double-layer tempered glass — the catalog names all three but doesn’t state which lid type is assigned to which specific SKU. Industry naming convention makes curved glass a reasonable fit for the Arc model and flat glass a reasonable fit for the Flat model; that mapping isn’t confirmed in the published spec sheet, so treat it as a factory question before it goes on a customer-facing sheet, not as a settled fact.

Why the Temperature Ranges Aren’t Identical Across the Line

Look closely at the table and one thing stands out: Arc (YD1200) and Combo (ZD1860) top out at 0°C, while Flat (PD1200) and Deep (SD1400) go up to 8°C. That’s not a rounding difference. A unit capped at 0°C is built for frozen-only merchandising. A unit reaching 8°C can handle a chilled zone as well, which is useful for a convenience store running one cabinet for both ice cream and chilled drinks rather than budgeting floor space for two separate units. Deep also runs colder at the bottom of its range (−23°C) than Flat (−20°C), despite sharing the same 1400×650mm base footprint — worth checking against the specific SKUs a project needs rather than assuming the two are interchangeable because the outer dimensions match.

Modular Connection: Building Multi-Unit Freezer Islands for Chain Buyers

All four sub-types support back-to-back or side-by-side modular connection, which is the feature that matters most for a supermarket or convenience chain buyer laying out a frozen-food aisle rather than a single cabinet. Connecting units end-to-end creates a continuous run without a visible gap between cabinets — standard practice in the category, and one the fridgefreezerdirect and ggmgastro-style retail listings dominating this keyword’s search results handle through add-on “head case” accessories rather than a manufacturer-specified connection method built into the base unit.

Four Mistakes Buyers Make When Specifying Island Freezers for Export

• Assuming all four sub-types share one temperature range. Arc and Combo are frozen-only up to 0°C; Flat and Deep reach 8°C. Confirm which range a project actually needs before locking in a model.
• Matching footprint without matching depth. PD1200 and SD1400 share the same 1400×650mm base but different depths (910mm vs 870mm) and different bottom-range temperatures — a swap based on floor plan alone can miss both.
• Assuming lid glass type is fixed per SKU. The catalog lists three lid options across the line without confirming a one-to-one SKU assignment. Get this in writing rather than assuming from the model name.
• Ordering single units for a planned multi-cabinet run. Back-to-back and side-by-side connection is available, but layout drawings for a connected run should be confirmed with the factory before production, not adjusted after units arrive.

R290, F-Gas, and Certification: What’s Confirmed and What Isn’t

All four island freezer models use R290, a natural refrigerant. That matters beyond the spec sheet: the EU F-Gas Regulation is steering commercial refrigeration away from high-GWP synthetic refrigerants, and the Montreal Protocol’s Kigali Amendment sets the broader global timeline for phasing down HFCs. R290 sits on the low-GWP side of that shift, which is relevant context for any buyer sourcing for EU-bound projects or markets following similar regulatory direction — though it’s industry background, not a Senlis-specific compliance claim.
The line carries CE marking, RoHS compliance, and ISO 9001-managed production. Certificate numbers and issuing bodies aren’t published — request that documentation directly for customs clearance or a tender submission.

Customizing an Island Freezer Order

OEM/ODM options apply across all four sub-types:

• Exterior color and branding
• Voltage and plug standard — 110V/220V/380V; US, EU, or UK plug types
• Cabinet size adjustments beyond the base four SKUs
• Internal shelving and lighting layout
• Packaging and user-manual language

What This Guide Doesn’t Confirm Yet

A few specifics aren’t published for this line, and this guide isn’t filling them in with estimates:

• Which lid glass type (curved, flat, or double-layer tempered) is assigned to which specific SKU
• Noise level in dB(A)
• Power draw or wattage
• Internal (as opposed to external) cabinet dimensions
• Certificate numbers and issuing bodies for CE, RoHS, and ISO 9001

Request these directly before they go into a customer-facing spec sheet.

Sourcing From the Manufacturer Behind the SKU

Senlis has built commercial refrigeration equipment since 2003 from a self-owned, 8,000+ m² production base in Shandong, China, producing more than 400 units a day under ISO 9001–managed processes. Each island freezer goes through laser cutting, stainless steel bending, laser welding, surface polishing, quality inspection, and packing before shipment. Sourcing directly from the manufacturer is also what makes the modular connection and OEM customization above practical to specify at order time rather than negotiate after the fact.

Requesting a Quote: What Happens After You Submit Specs

• Inquiry — submit sub-type, quantity, and whether units need to connect in a run, plus destination country, through the lead form (Name, Country, E-mail, Company) or WhatsApp.
• Quotation — pricing is calculated per project; there’s no published price list, and a number typically comes back within 24 hours.
• Design — confirm voltage, plug standard, lid glass type, and any custom connection layout.
• Production — units are built to the confirmed configuration.
• Inspection — cooling stability, energy efficiency, and noise are tested pre-shipment.
• Delivery & Support — units ship with ongoing support available after arrival.

FAQ

 What’s the difference between the Deep and Flat island freezers?

SLS-SD1400 (Deep) and SLS-PD1200 (Flat) share a 1400×650mm base footprint but differ in depth (870mm vs 910mm) and temperature range (−23–8°C vs −20–8°C). They’re not interchangeable despite the matching footprint.

Can island freezers be connected into a continuous run?

Yes — all four sub-types support back-to-back or side-by-side modular connection. Confirm the connection layout with the factory at the design stage of the quote process, before production.

 What refrigerant do these use, and does it matter for EU imports?

All four models use R290, a low-GWP natural refrigerant. That aligns with the direction of the EU F-Gas Regulation and the Montreal Protocol’s Kigali Amendment on phasing down higher-GWP refrigerants, though this is industry context rather than a specific compliance certification Senlis holds.

 Which island freezer model reaches the coldest temperature?

SLS-YD1200 (Arc) and SLS-ZD1860 (Combo) both go down to −25°C, colder than the Flat (−20°C) and Deep (−23°C) models — though those two also reach up to 8°C on the warm end, which Arc and Combo don’t.

Is pricing published for the island freezer line?

No. Pricing is quoted per project based on model, quantity, and destination market, typically returned within 24 hours of inquiry.
